MBP was having problems with out of bounds memory operations with the way the cam dir was handled. sf::vector3f -> float3 and while accessign the Zth element. I'm assuming it was because of some weird backend stuff regarding that gentypeOdds are actually gentypeOdds + 1. Converted write_imagef's to write_imageui's though I don't think that really helps anything. Fixed the bottom half of the screen getting cut off. View matrix import error. Fixed problem the MBP had with negative values during device init, that was a weird one.

WORKING! Awesome! It now casts fully inside the gpu,

context is then switched to gl and then rendered via sfml.
It has no loop, no controls, and the aspect ratio is off,

Large amount done. OpenCL is almost completely abstracted out to the class
...
from init to kernel compilation. Next will be getting buffer handling, executing, and reading done.
Changed the kernel to a more minimal example.
Added a jump table for error codes and an assert function for error checking.
Added a routine to compare all the available cl devices and platforms, chooses the high clock of either the GPU or CPU.

There we go! The raycaster now has a camera that renders without distortion and can be pitched, yawed, and moved on the XYZ axis. I'm not sure now if I want to: Add lighting, improve performance, or start working on porting it to OpenCL

Ahh! It works!! The camera is great now, it yaws and pitches perfectly, just need to limit it to 180 -> -180 on the pitch. There is still a problem when viewing in the negative angles, and as you move the camera closer to 0 things get weird and distorted. But the transfer over to a spherical camera point and a cartesian view plane worked fantastically

alright, tried a different method of assigning voxel step directions and I

think it's working. The 3 negative walls are still very flat, and the
