Z-buffering - Wikipedia

WebA depth buffer, also known as a z-buffer, is a type of data buffer used in computer graphics to represent depth information of objects in 3D space from a particular perspective. Depth buffers are an aid to rendering a scene to ensure that the correct polygons properly occlude other polygons. WebAdvanced OpenGL .

If you really want to specify the depth with a uniform variable, you need to have the uniform variable in the vertex shader, and use it to calculate gl_Position.This approach from your question looks fine: javascript print image from url
