Hi,
I would like to set colors firstly with my color_buffer_
glColorPointer(3, GL_FLOAT, 0, color_buffer_);
glVertexPointer(3,GL_FLOAT, 0, faces_);// Vertex Pointer to triangle array
glNormalPointer(GL_FLOAT, 0, normale_); // Normal pointer to normal array
glDrawArrays(GL_TRIANGLES, 0, totalconnectedtriangles_);
and then my fragment shader only to change the red value of my texture
#version 410
layout(location = 0) out vec3 color_out;
precision highp float;
void main()
{
float z = 0.3f;
color_out = vec3(z, green_value_from_color_pointer(NO CHANGE) , blue_value_from_color_pointer(NO CHANGE))
}
Actually my fragment shader is able to set all the colors but I want to set only the red one.
Any help will appreciated if you have an idea
EDIT: please mod delete this thread I post it in the right section now
