Hi,
How can I pass vertices in GLSL1.4 shaders
How can I pass values to "in vec4 vertex"
Code example.
Code:
#version 150
uniform mat4 projectionMatrix; //Specifies that the value is passed to the
shader from the
application and is constant across a given primitive.
uniform mat4 modelViewMatrix;
in vec4 vertex;//Specifies that the variable is an input to the shader stage.
in vec3 normal;
out vec3 fragmentNormal;
out vec3 fragmentEye;//Specifies that the variable is an output from a shader
stage.
void main(void)
{
fragmentNormal = (modelViewMatrix*vec4(normal, 0.0)).xyz;
fragmentEye = (modelViewMatrix*vertex).xyz;
fragmentEye = -normalize(fragmentEye);
gl_Position = projectionMatrix*modelViewMatrix*vertex;
}
Thank you!
Cheers,
John
