I am making project of cubesphere Earth. I implemented vertex and fragment shaders for textures and it worked fine (with camera movement). I wanted to add a passthrough geometry shader but i cant get it to work.
Vertex shader
#version 450 core
layout (location = 0) in vec3 position;
layout (location = 1) in vec2 textureCoords;
out vec2 textCoords;
uniform mat4 model;
uniform mat4 view;
uniform mat4 projection;
void main()
{
gl_Position = projection * view * model * vec4(position, 1.0);
textCoords = textureCoords;
}
Geometry shader
#version 450 core
layout (triangles) in;
layout (triangles, max_vertices = 3) out;
in vec2 textCoords[];
out vec2 TextCoords;
void main()
{
int i;
for(i = 0; i < gl_in.length(); i++)
{
gl_Position = gl_in[i].gl_Position;
TextCoords = textCoords[i];
EmitVertex();
}
EndPrimitive();
}
Fragment shader
#version 450 core
in vec2 TextCoords;
out vec4 fragmentColor;
uniform sampler2D earth;
void main()
{
fragmentColor = texture(earth, TextCoords);
}
I used shader class from learnopengl, and only thing i changed in Main was geometry shader path in Shader constructor.
