The way I learnt to send a texture to a shader is more or less
//Use program //Bind texture to the texture unit to its appropriate target glActiveTexture(GL_TEXTURE0 + texture_unit); glBindTexture(target, textureID); //Get the uniform location in the program and attach the texture unit GLuint location = /*get the location somewhow*/; glUniform1i(location,texture_unit);
However when dealing with buffers and SSBOS rather than trying to find a location through a string name, the object is declared as:
layout(std430, binding = 2) buffer texture_meta_data
For example. This means that the SSBO is to be bound at binding point 2
And then on the C++ side one does something like
glBindBufferBase(GL_SHADER_STORAGE_BUFFER, 2, SSBOID);
To bind the object to the binding point.
How can you do the same with textures?
