glsl-basic-vertex-shader

GLSL snippet for a generic vertex shader for use with glslify. Includes standard components like model, animate, view, and projection matrices. Designed for standalone use. You might find it useful if you find yourself writing this boilerplate shader, or something similar, a lot.

install

Add to your project with

npm install glsl-basic-vertex-shader

usage

Inside your vertex shader just call

#pragma glslify: main = require('glsl-basic-vertex-shader')

components

Make sure you define all attributes and uniforms. If you don't need to use any of the matrices just set them to the identity matrix. The varying variables can be used in your fragment shader.

attributes

• vec3 position input vertex position
• vec3 normal input vertex normal

uniforms

• mat4 projection projection matrix
• mat4 view view matrix
• mat4 model model matrix
• mat4 animate animation matrix
• mat3 modelNormal transpose inverse of model matrix
• mat3 animateNormal transpose inverse of animation matrix

varying

• vec3 vposition computed vertex position
• vec3 vnormal computed vertex normal
