baseNormalShader()

void beforeVertex

Called at the start of the vertex shader.

Vertex getObjectInputs

Update the vertex data of the model being drawn before any positioning has been applied. It takes in a Vertex struct, which includes:

• vec3 position, the position of the vertex
• vec3 normal, the direction facing out of the surface
• vec2 texCoord, the texture coordinates associeted with the vertex
• vec4 color, the per-vertex color The struct can be modified and returned.

Vertex getWorldInputs

Update the vertex data of the model being drawn after transformations such as translate() and scale() have been applied, but before the camera has been applied. It takes in a Vertex struct like, in the getObjectInputs hook above, that can be modified and returned.

Vertex getCameraInputs

Update the vertex data of the model being drawn as they appear relative to the camera. It takes in a Vertex struct like, in the getObjectInputs hook above, that can be modified and returned.

void afterVertex

Called at the end of the vertex shader.

void beforeFragment

Called at the start of the fragment shader.

vec4 getFinalColor

Update the final color after mixing. It takes in a vec4 color and must return a modified version.

void afterFragment

Called at the end of the fragment shader.
