Recreate playstation graphics in a 3d program?

Walou · Aug 2014

Hi everyone, i've been searching about this for a while but came with no good results but a japanese pc game with the similar graphics of a ps1 game, but i dont know how he did it.

I'm not talking about the lowpoly models or the low res textures or screen resolution.

I'm talking about the shaky polygons/vertices and weird texture deformation you can see in every ps1 game.

If anybody knows of a way to do it in any program (renderer or real time) please share it.

Heres what im talking about
Another example

it could be imprecision in the vertex lerping when animating

IIRC they couldn't use texture filtering, so it's all Nearest Neighbor.

I also recall textures not being sampled correctly in perspective, so sometimes you would get pixels swimming as they went across triangle borders. Especially when deforming meshes.

The PS1 had no perspective correction on textures, hence the texture "swimming" on diagonal edges, I think it was all software.

Texture swimming on PS1 games didn't have perspective-correct texturing. This wasn't helped by the fact that often textures had to be small (32x32, 64x64) and would be applied (and tiled) to large surfaces of just 2 triangles. You could reduce the swimming by subdividing the mesh more, but it would always be there and more polys would also break the budget.
