The test kernel now draws a few pixels to the screen. Pretty much set up nowto start writing the raycaster

Continuing on adding argument handling.
...
Added a small sample texture and sprite which can be handed over to either gl or cl and then handed back. It can then be rendered.
Changed to just an array of floats for the view matrix

Getting things passed over to cl. No vector4 datatype in sfml,

and cl only passes by even numbers of vectors. Update to 2.4? or
make my own sf::Vector4?

Added args and buffer handling, but now clEnqueueNDRangeKernel is failing
...
with the error invalid command queue. Haven't seen that one before, and
cursory google suggests it's a problem with MBP's. Fun! I'll keep taking
a look, and I'll try it on my windows machine here soon

Switched names, thinking about how to do kernel args, and buffers.
...
Need to do a bit more reading on how to set up interop.
Also need to figure out the buffer thing for regular primative buffers, and also image buffers

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.

Added a compilation routine, probably will abstract all this out into

it's own class / function. Added a small kernel that I got from a tutorial
to test the compilers error codes. Added a small notes file with error
codes. Added some error checking for the error codes

Cleaned up the cmake file. Imports SFML, CL, and GL now.

But I'm not sure how well it will work on windows so I need
to test that out. Also added a stack overflow snippet to
check your compute devices and give their opencl version

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
lower XYZ numbers still distort the viewport

So it's rendering pretty much perfectly in the XYZ+ range but things break

down when I start hitting negative values. I have a feeling this is going
to be a lot of trial and error. Oh well
