So what I want to do is rotate the model.
this is what I start with
model = glm::translate(glm::mat4(1.0), modelPos[i]) * glm::scale(glm::mat4(1.0), scale)
I want to rotate the roll so I should just be able to use
model = glm::translate(glm::mat4(1.0), modelPos[i]) * glm::scale(glm::mat4(1.0), scale) * glm::rotate(model, glm::radians(therot[i]), glm::vec3(1, 0, 0));
but I get the error that says that it has to be a float for glm::radians
model = glm::translate(glm::mat4(1.0), modelPos[i]) * glm::scale(glm::mat4(1.0), scale) * glm::rotate(model, glm::radians(90.0f), glm::vec3(1, 0, 0));
this does not work when the float aspect is explicitly applied
Has model been initialised? In the first example you’re using an identity matrix as the base transformation, in the second and third you’re using model. Also, if you’re using a base transformation, it would normally be in the left-most function. As written, the code calculates
model = T * S * model * R;
where T, S, R are the translation, scale and rotation matrices respectively.
The first argument is so that you can accumulate transformations in a manner similar to legacy OpenGL, i.e.
glm::mat4 model = glm::mat4(1.0);
model = glm::translate(model, modelPos[i]);
model = glm::scale(model, scale);
model = glm::rotate(model, glm::radians(90.0f), glm::vec3(1, 0, 0));
Each successive translation is appended on the right, so the above calculates model = T * S * R.
