output block

The output block specifies the values to be passed to the next shader stage. You can also define roles by attaching semantics. Specify the name of the target shader stage next to output (e.g., vertex or fragment).

Type	Semantic Name	Description	Required
vec4	VS_OUT_POSITION	Can be specified in the vertex shader. Output vertex position	Required
vec4	FS_COLOR	Can be specified in the fragment shader. Output color	Required
float	FS_DEPTH	Can be specified in the fragment shader. Output depth	Optional

output vertex
{
    vec4 outPos : VS_OUT_POSITION;
    vec3 WorldNormal;
    vec3 WorldPos;
    vec2 uv;
}

output fragment
{
    vec4 outColor : FS_COLOR;
    float outDepth : FS_DEPTH;
}
