Project 5 - Render Buffers
In this project we will explore the render-to-texture features of OpenGL.
Your program must take the name of the .obj file as its first command-line argument.
The object should be rendered using the diffuse texture, if one is specified in the mtl file.
Instead of rendering the object directly to the OpenGL viewport, the object should be renderered to a texture via a render buffer.
You can use the GLRenderTexture class for generating and using a render buffer.
Display the rendered texture by mapping it on a square-shaped plane.
As before, left mouse button (and drag) should adjust the camera angles, and right mouse button (and drag) should adjust the camera distance, used for rendering the object to the texture.
If the ALT/Option key is pressed, the left and right mouse buttons (and drag) should control the same view parameters for rendering the plane.
Add some small constant to color of the plane to separate it from the background color.
An example view.
The teapot image is a texture on the plane.
Additional Requirements for CS 6610 Students
The rendered texture should use bilinear filtering for magnification and mip-mapping with anisotropic filtering for minification.
