Depth Test depthtest
- Enables and disables the Depth-Test. If the depth-test is disabled, depths values aren't written to the Depth-Buffer.
Depth Test Function depthfunc
- ⊞ - The depth value of the pixel being drawn is compared to the depth value currently in the depth-buffer using this function. If the test passes then the pixel is drawn to the Frame-Buffer. If the test fails the pixel is discarded and no changes are made to the Frame-Buffer.

Write Depth Values depthwriting
- If Write Depth Values is on, pixels that pass the depth-test will write their depth value to the Depth-Buffer. If this isn't on then no changes will be made to the Depth-Buffer, regardless of if the pixels drawn pass or fail the depth-test.
[edit]
Discard Pixels Based on Alpha alphatest
- This enables or disables the pixel alpha test.
Keep Pixels with Alpha alphafunc
- ⊞ - This menu works in conjunction with the Alpha Threshold parameter below in determining which pixels to keep based on their alpha value.

Alpha Threshold alphathreshold
- This value is what the pixel's alpha is compared to to determine if the pixel should be drawn. Pixels with alpha greater than the Alpha Threshold will be drawn. Pixels with alpha less than or equal to the Alpha Threshold will not be drawn.

An Operator Family that associates a shader with a SOP or Geometry Object for rendering textured and lit objects.
The term "Frame" is used (1) in the Timeline, (2) as a time-unit in CHOPs, (3) as a time-unit in TOPs, and (4) with movies images which are read and created with TOPs.
The connection of an output of one node to the input of another node in a network. In contrast, see Link.
An Operator Family that creates, composites and modifies images, and reads/writes images and movies to/from files and the network. TOPs run on the graphics card's GPU.
