// Renderer needs to handle the distinction between a few difference circumstances.
|
|
// A.) The machine supports OpenCL and cl_khr_gl_sharing
|
|
// Everything is normal, rendering is handled on-gpu
|
|
// B.) The machine support Opencl and NOT cl_khr_gl_sharing
|
|
// For every frame we have to pull the screen buffer from the GPU's memory
|
|
// C.) The machine does not support OpenCL
|
|
// We must use the fallback software renderer
|
|
|
|
// Renderer will hold its own CL_Renderer class which contains all of the data
|
|
// and functionality that the CL_Wrapper class currently does, but with the
|
|
// intent of leaving it specialized to only the raycaster. Any further OpenCL
|
|
// work can use its own class

// hold the current map, camera, and light objects. The renderer will
