First of all let me say that I really appreciate the efforts to help.

Hmm... aren't there many different combinations of axis angle to get to achieve a certain rotation? So if I get two...

The problem with that is that if I take the absolute value of sin(theta) or cosine(theta) on each individual axis, the sin(theta) for example might be very close even though the object is facing...

I'm not sure I understand your response. R1 is a matrix? Because my rotation in 3D is either described by a quaternion or by a 3x3 matrix. I can't quite see how your calculation will give me a...

### 3D rotation mismatch calculation

I am trying to figure out a way to compare the 3D rotation of two objects and find a measure of HOW MUCH they are mismatched. The only thing I have is I have the two objects' matrices or quaternions....

### Re: GLM order of transforms

I was under the impression that GLM::translate , translates the 1st argument based on the 2nd vector. Based on that assumption I thought I was creating a mat4 from the quaternion and then translating...

### GLM order of transforms

I have an object which I first want to rotate (about it's own center) then translate it to some point. I have a glm::quat that holds the rotation and a glm::vec3 that holds the point to which it...

### IDEA: Tag Tutorials that do things the "new way"

Hello, beginner OpenGL developer and first time poster.

I like how OpenGl is picking up pace and is now on par, or even better than some other graphic APIs. However there's a major obstacle to new...
