Hi everybody,

i'm a newbie user of processing. I've two questions for the community, unfortunately I've not found any answer on previous topics.

- I've drew a model on a scene using 3D primitive. Is it possible to have a 2D representation of its depth map?

- Is it a way to have depth map from an imported OBJ model?

thank you.

Look into the OBJ loader library. I haven't used it before but i know you can load geometry and texture data of OBJs into processing with that library. As for making a 2d representation i'm not sure if the library does that naturally but you could probably create your own using the coordinates of each point.

x and y get drawn on screen and map Z to a number that becomes a color for instance using the map function

something like this theoretically.

float col = map(zCoord, minCameraDepth, maxCameraDepth, 0, 255);
stroke(col);
point(xCoord, yCoord);
