I'm trying to do texture mapping in GLSL 150 and OpenGL 3.3
Here are my shaders I've tried my best to get this correct as possible hopefully this is :)
I'm guessing you want to know what the problem is well my texture shows but not in its fullest form just one section of it not the full texture on the quad.
All I can think of is its the texture cordinates in the main.cpp which is at the bottom of this post.
FRAGMENT SHADER
#version 150
in vec2 Texcoord_VSPS;
out vec4 color;
// Values that stay constant for the whole mesh.
uniform sampler2D myTextureSampler;
//Main Entry Point
void main()
{
// Output color = color of the texture at the specified UV
color = texture2D( myTextureSampler, Texcoord_VSPS );
}
VERTEX SHADER
#version 150
//Position Container
in vec3 position;
//Container for TexCoords
attribute vec2 Texcoord0;
out vec2 Texcoord_VSPS;
//out vec2 ex_texcoord;
//TO USE A DIFFERENT COORDINATE SYSTEM JUST MULTIPLY THE MATRIX YOU WANT
//Main Entry Point
void main()
{
//Translations and w Cordinates stuff
gl_Position = vec4(position.xyz, 1.0);
Texcoord_VSPS = Texcoord0;
}
