sf::Shader and glm::mat4
« on: December 16, 2014, 06:52:04 pm »
Hi! How to pass in shader matrix 4x4?
vert.glsl:
attribute vec4 a_position;
attribute vec4 a_color;

uniform mat4 u_MVP;

varying vec4 v_color;

void main()
{
        v_color = a_color;
        gl_Position = u_MVP * a_position;
}
 
main.cpp
glm::mat4 projectionMatrix;
glm::mat4 viewMatrix;
glm::mat4 modelMatrix;
sf::Shader shader;
//...
if (!shader.loadFromFile("res/shaders/vert.glsl", "res/shaders/frag.glsl"))
{
        exit(1);
}
//...
sf::Shader::bind(&shader);
shader.setParameter("u_MVP", glm::value_ptr(projectionMatrix * viewMatrix * modelMatrix)); // error
//...
sf::Shader::bind(NULL);
 
Error in shader.setParameter. Please tell me the solution?

What about providing the error?

No need to ask, if there was, it would be visible in the issue itself ;)

Until something is done on our side, I don't think it is even possible.
