Direct3D 8 - Vertex Shader (Microsoft)

Last edited 2026-01-27

A programmable vertex shader is made up of a set of instructions that operate on vertex data.

Registers transfer data in and out of the ALU.

Additional control can be applied to modify the instruction, the results, or what data gets written out.

Fusion does not pass a matrix for the vertex shader. Vertex Shader for Direct3D 8 may not be working at the moment for this.

This section is incomplete, more information coming soon.

Version Differences

Each version has different limitations, when writing a shader decide which version will be ideal for your effect.

Registers

Contains a list of the various registers used by the ALU shader.
