Questions tagged [depth-buffer]
Depth buffer stores a depth (z-coordinate) of a rendered pixel of a 3D scene. Depth buffer is used in Z-buffering (management of image depth coordinates). Because of this depth buffer is often called Z-buffer.

In OpenGL, how can I discover the depth range of a depth buffer?
I am doing a GL multi-pass rendering app for iOS. The first pass renders to a depth buffer texture. The second pass uses the values in the depth buffer to control the application of a fragment shader. ...

Using full resolution of depth buffer for 2D rendering
I'm working on a front-to-back renderer for a 2D engine using an orthographic projection. I want to use the depth buffer to avoid overdraw. I have a 16-bit depth buffer, a camera at Z=100 looking at Z=...

Shadow Mapping and Transparent Quads
Shadow mapping uses the depth buffer to calculate where shadows should be drawn.
My problem is that I'd like some semi transparent textured quads to cast shadows - for example billboarded trees. As ...

What would be a good filter to create 'magnetic deformers' from a depth map?
In my project, I am creating a system for deforming a highly detailed mesh (clothing) so that it 'fits' a convex mesh.
To do this I use depth maps of the item and the 'hull' to determine at what point ...

using heightmap to simulate 3d in an isometric 2d game
I saw a video of an 2.5d engine that used heightmaps to do zbuffering.
Is this hard to do? I have more or less no idea of Opengl(lwjgl) and that stuff.
I could imagine, that you compare each pixel ...
