示例1: loadProgram
void loadProgram(Program &p, const std::string& name) {
//Initializes a Program object
p.create();
//Gets the path to the vertex shader (ending in ".vsh")
string sv = rh.pathToResource(name, "vsh");
// cout << "path of vertex shader is: " << sv << endl;
//Compiles the vertex shader and attaches it to our Program object
p.attach(rh.contentsOfFile(sv), GL_VERTEX_SHADER);
//Binds attribute variables to a particular ID
glBindAttribLocation(p.id(), posLoc, "vertexPosition");
glBindAttribLocation(p.id(), colLoc, "vertexColor");
//Gets the path to the fragment shader (ending in ".fsh")
string sp = rh.pathToResource(name, "fsh");
// cout << "path of vertex shader is: " << sp << endl;
//Compiles the fragment shader and attaches it to our Program object
p.attach(rh.contentsOfFile(sp), GL_FRAGMENT_SHADER);
//Links the Program object to the GPU so that it can be activated when needed
p.link();
}示例2: loadProgram
void loadProgram(Program &p, const std::string& name) {
//can't link shaders unless a vao is bound...
//bindDefaultVAO();
p.create();
string sv = rh.pathToResource(name, "vsh");

string sp = rh.pathToResource(name, "fsh");

}示例3: loadProgram
void loadProgram(Program &p, const std::string& name) {
