playstation 1 graphics effect

[Foxhound]

Hey there fellow houdini cult members!

as the title says i am trying to "emulate" ps1 graphics, i figured out (at least i think i did) the affine texture warping part.

//get a matrix with the camera's transforms
string cam = "/obj/cam1";
matrix camMatrix = optransform(cam);

//extract out the camera position as a vector
vector cdir = {0.0,0.0,0.0}*camMatrix;
cdir = cdir;
vector raydir = normalize(v@P-cdir);


//Manipulate the UV coordinates for Affine Texture Mapping
float affineScale = length(raydir);//Scaling factor based on the viewing direction to the camera
v@uv *= affineScale;//Scale the UV coordinates

though i am struggling to nail it, it kinda works but the effect is not as visible as i expected. also i feel like i am missing quite some steps to really get that ps1 look and feel.



If you are down to help me figure this out i'd be very thankful and future houdini ps1 enthusiast might have a post to look at!

have a good one!
