Draw order in 3D

[jeremydouglass]

The issue above was with translateZ(-150) vs translateZ(150). So a question of which direction is forward / back.

Also notice that coordinates when using PeasyCam work differently than the default 3D cam.

Even once this is worked out:

Note however, with transparent object 3D CAN still sometimes have problems with drawing behind-things in front of in-front things. For fixing that, use hint().

Program to test hint() with transparency

A small Processing program to test the effect on transparency of enabling and disabling these settings: hint(DISABLE_DEPTH_TEST); // or ENABLE_ hint(DISABLE_DEPTH_SORT); // or ENABLE_ hint(DISABLE_DEPTH_MASK); // or ENABLE_ [Screenshot%20from%202018-10-11%2016-18-55] boolean b[] = new boolean[3]; void setup() { size(800, 600, P3D); hint(DISABLE_DEPTH_TEST); hint(DISABLE_DEPTH_SORT); hint(DISABLE_DEPTH_MASK); } void draw() { background(255); fill(0); text("DEPTH_TEST " + b[0]…

This can also apply to strokes – so if you are rendering a sphere with strokes, that can be the issue. See hamoids demo sketch and try clicking settings on and off to get a sense of how strokes can pop-through in surprising ways.
