Hi3d: Hyper3D Rodin Planter Review and Base Check

For readers looking for hi3d, this hands-on planter comparison shows why a visible inner floor matters more than a watertight mesh check. It also explains when SupaVoxel’s more convincing foil exterior may be the better starting point.

Disclosure: this is an independent hands-on test. Both tools were run on ordinary customer accounts; neither company supplied review access or saw this piece before publication.

The test brief was a blue crumpled-foil planter, not a symmetrical vase or merely a good front-facing render. I gave the same single image to Hyper3D and SupaVoxel, opened their actual textured downloads and looked inside from above before imagining soil or a printer. The most important finding is a hole you can see, even though a standard mesh check says both exports are topologically watertight.

My verdict in 60 seconds — for an as-delivered planter candidate, I would start with Hyper3D Gen-1.5’s visible inner floor, not SupaVoxel’s visibly through-open cavity. This is a shape decision, not a certification that either file contains water or soil. Hyper3D Gen-1.5 shows a blue inner floor. The actual SupaVoxel Original size GLB shows white scene background through the lower opening. SupaVoxel unquestionably produces more convincing irregular foil on the outside; for a visual study or prop that will be intentionally remodeled, I would start there. But topologically watertight does not mean “can hold soil,” and I would not send its as-delivered shape to a planter print queue. Neither model was sliced, printed, filled or leak-tested.

Here is my eight-line decision card for the as-delivered container starting point. Each measured or visible difference names the work it leaves to do; the floor is a gate, not a weighted point:

Visible inner floor — Hyper3D yes, SupaVoxel shows background through cavity — the decisive functional-shape difference.
Outer foil irregularity — Hyper3D broad near-mirrored folds, SupaVoxel varied crossings — SupaVoxel clearly wins the art brief.
Welded watertight topology — both yes — a real tie that cannot resolve the floor question.
Welded nonmanifold / boundary edges — 0 / 0 for both — clean edge counts do not create a base.
Degenerate faces — 0 vs 12 — Hyper3D has the tidier triangles here.
Sliver faces — 610 vs 8,408 — extra sampling does not guarantee cleaner topology.
Mean edge at 120 mm longest side — 1.1448 vs 0.3841 mm — SupaVoxel carries finer fold detail.
Physical leak, wall and slice test — neither performed — no one has earned “ready to plant.”

A vessel and a convincing foil surface are different commissions. A useful decision must name which of those jobs is being evaluated.

What did the single source actually show?

Both products received this identical 1,647,256-byte independently generated blue-container PNG; its dark cavity does not prove that the pictured object has a floor.

There is no plant, no second view and no unambiguous reference for the bottom. The single photograph asks for irregular crisscrossing crumples on an open-rimmed blue cylinder. It does not tell either generator how to build a watertight container in use. Both uploads matched the same input bytes, but the tools’ own descriptions and settings differed. I am comparing the delivered results, not claiming an isolated test of a hidden algorithm. My first check is what a gardener would do before reading a triangle count: look into the opening.

What happened when I looked down into SupaVoxel’s model?

The SupaVoxel Original size GLB has a ring wall; the white background is visible through its lower central passage.

The model pictured is the actual 58,065,236-byte browser Original size GLB, not a smaller CDN copy. White viewer background is visible through its central passage. That is not an open-mesh-boundary claim: a closed-surface tube can be topologically watertight while soil falls through its middle. A usable pot needs an added, joined inner base, a floor-thickness check, slicing and a physical test. None happened here; the repair labor and revised material quantity are unmeasured.

Did Hyper3D put a floor in the same place?

The Hyper3D Gen-1.5 PBR member shows a blue interior floor instead of white background at the matched overhead angle.

Yes. That apparent bottom makes Hyper3D a better container candidate despite less chaotic exterior folds. A blue floor in a render is not proof of thickness, strength, drainage or leak resistance; neither file was printed or filled. At a common 120 mm longest bounding-box side, their boxes are 92.61 × 120 × 92.8 mm and 91.3 × 120 × 92.26 mm. Those figures do not establish usable interior capacity. But Hyper3D passes the first visible floor check.

Why did the watertight check say “yes” to both?

Hyper3D’s lower-density wireframe belongs to the actual 120,000-triangle Gen-1.5 PBR export, not a blocked million-face preview.

SupaVoxel’s dense wire cannot reveal whether the model’s central passage is a useful container cavity.

UV seams duplicate vertices: raw boundaries read 61,004 vs 104,794. Weld those seam duplicates and both files become one face-connected, consistently wound, watertight shell with zero boundary/nonmanifold edges. Yet a doughnut is a closed surface too. A manifold tube’s central passage is not a bowl bottom. The paired top images show Hyper3D’s visible floor and SupaVoxel’s through-opening. “Watertight mesh” cannot be stretched into “holds water.”

Does SupaVoxel at least make the folds in the brief?

Without blue PBR paint, SupaVoxel still has crossing ridges and recesses of varied size; its crumpling is geometric.

Absolutely. Without materials, SupaVoxel’s differently sized diagonal facets still cross; Hyper3D’s gather around a mask-like center spine. That is what the images show, not a claim that extra faces cause accuracy. The files have 1,500,000 vs 120,000 triangles. At the 120 mm longest-side scale, average edge lengths are 0.3841 vs 1.1448 mm — about 2.98× finer sampling. A 0.4 mm FDM nozzle is context, not proof those folds survive printing.

What did Hyper3D do to the silhouette?

Hyper3D’s textured front shows its central near-mirrored ridge even before the clay check.

SupaVoxel’s textured front retains less predictable crossed ridges; both image pairs use the tested exported files.

The Hyper3D clay shape has a rim and real facets, but its central ridge and paired hollows feel closer to a mask than accidental foil.

Hyper3D is not a blank cylinder: it has angular ridges. But front and rear organize them around a near-bilateral axis rather than the reference’s unruly crossings. A digital prop artist gets better foil from SupaVoxel. A maker needing a container instead gets a floor-design and joining task with SupaVoxel, of unmeasured duration. Hyper3D may need aesthetic sculpting; it already shows the inner bottom.

Which mesh has more actual cleanup noise?

At the same seam-welded analysis settings, Hyper3D has 0 degenerate faces and 610 sliver faces. SupaVoxel has 12 degenerate and 8,408 sliver faces. Both have zero welded nonmanifold edges. This is a real rival win in triangle hygiene, not a hidden footnote. SupaVoxel’s sliver count is about 13.8 times Hyper3D’s, even though its overall triangle count is 12.5 times higher. A sliver count by itself does not tell me whether a slicer rejects the object or whether cleaning every sliver is required; no such test was run. It does tell me not to sell “1.5 million faces” as unqualified print quality. For a digital close-up I can trade some cleanup headroom for folds I want. For an automated manufacturing pipeline, I would inspect the 8,408 first and keep the need for a new interior floor on the job ticket.

Can potential overhang area decide the print bill?

Hyper3D’s lower exterior folds make a different side profile; the support calculation is an orientation screen, not a slicer output.

SupaVoxel retains angular exterior relief from the side, but no printer-generated support structure was measured.

I normalized each file so its longest bbox side is 120 mm, assumed world Y is up and counted faces whose normals point within 45° of downward −Y. That flags 5,524.6 mm², or 8.9602%, on Hyper3D and 1,703.2 mm², or 2.4824%, on SupaVoxel. The difference is 3,821.4 mm² of potentially downward-facing surface under that orientation, not “3,821.4 mm² fewer required supports.” A face resting on the bed may be counted, and rotating the print or adding SupaVoxel’s missing visible floor changes the result. Without a slicer, resin supports, machine, build orientation and a completed usable geometry, I cannot convert this screen into printing minutes or support dollars. It points to what I would inspect next, not which model I would quote to a client.

What does the solid-fill resin estimate actually price?

For the current topologically closed shapes at the same longest-side 120 mm scale, mathematical enclosed volumes are 487.23 cm³ Hyper3D and 193.89 cm³ SupaVoxel. A completely solid pour at the illustrative $35 per liter gives $17.05 vs $6.79. That $10.26 gap is not a saving on two equal, usable planters. SupaVoxel’s modeled passage lacks the observed floor and would need new geometry; Hyper3D’s apparent bottom still requires thickness and physical validation. Hollowing, drainage, supports, waste and shrinkage are excluded. A structurally valid signed volume answers how much these exported closed surfaces enclose, not how much resin a sensible planter will consume after redesign. The exchange rate for SupaVoxel’s excellent crumples includes an unknown base-design and verification cost; I will not erase that with a neat but inapplicable $6.79 number.

Is the attractive million-face Hyper3D preview part of this comparison?

Hyper3D Gen-2.5’s separate million-face preview cost an isolated 0.5 credit, then explicitly required a subscription for GLB download on the tested Free account.

No. Hyper3D’s accessible analyzed mesh is Gen-1.5, 120,000 triangles, extracted as a PBR GLB from its successful ZIP. A separate Gen-2.5 preview claimed one million faces and “Print-Ready” inside the interface but supplied no downloadable file to this Free account after the 0.5-credit debit. I will not transfer that preview’s claimed quality or badge onto the Gen-1.5 model. Hyper3D’s second, Gen-1.5 run incurred another isolated 0.5 credit at geometry Confirm; independently checked Material Generate and Confirm cost zero more in this case. Those credits are not comparable to SupaVoxel’s independently matched three-credit transaction: different ledgers, no dollar exchange rate. For a shop, the only candidate I can inspect is the file actually delivered.

How much file did each export really transfer?

SupaVoxel’s actual browser Export → GLB → Original size produced the 58,065,236-byte file analyzed here, not the separate 8,499,144-byte CDN resource.

Hyper3D’s webpage transferred a 21,471,080-byte ZIP containing a 14,038,528-byte PBR GLB and a Shaded variant. SupaVoxel’s tested UI selection transferred 58,065,236 bytes as one Original size GLB. The SupaVoxel same-task compressed CDN file is 8,499,144 bytes but was not a measured click on its Compressed menu; a separate 44,556,092-byte local analysis derivative was not a browser export either. At hypothetical ideal 12 Mbps, the actual UI payloads need 14.31 vs 38.71 seconds of pure transfer. A smaller Hyper3D file is a genuine win. For a digital foil close-up I may accept the larger SupaVoxel file for better exterior creases; for a planter the more pressing cost is designing the missing visible floor. File size and function must not be smuggled into the same metric.

Final verdict: which starting shape fits each brief?

For an apparently bottomed planter candidate, Hyper3D Gen-1.5. It shows the blue inner floor and has a clean welded shell in this particular pair. I would still test wall and floor thickness, slice, print and check whether a real object handles soil or water; none of that has happened. For an irregular foil art object destined for digital display or deliberate redesign, SupaVoxel: its asymmetrical crossings make the exterior more compelling even without texture. Its welded watertight flag is not permission to claim container usability. That is the genuine rival-win and exchange rate, not a “both have pros and cons” dodge.

Use SupaVoxel when the foil surface is the product

If your commission prizes jagged, unpredictable creases and you can budget a floor-design stage before any physical use, start with SupaVoxel. Rotate the result and inspect it from overhead before ordering prints. This case delivers a stronger irregular surface, not a soil-holding or water-holding vessel. If your brief requires a usable bottom from the first downloadable model, this paired run gives Hyper3D Gen-1.5 the more relevant initial shape.

How I tested it. The identical source PNG went into both products. I used Hyper3D’s legally downloaded Gen-1.5 PBR member and SupaVoxel’s genuine browser Original size GLB, rendered from repeatable front, rear, side and top viewpoints. File counts and seam-welded topology are measured; fold and floor observations are from matched rendered images, not a measured watertightness-of-vessel test. The 120 mm normalization scales the longest side, and resin, transfer and batch figures require their stated hypothetical assumptions. Neither print, slicer, minimum wall, water/soil retention, completed base repair nor reference-image publication rights were verified.
