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.

opencl has no rand, SO rand method to make fog a little better

Changed to non branching algo, sped up a good 30-50 ms at the current max
...
ray dist. Also changed bounds checking a little, not sure if it's faster

mouse and camera movement work, stress testing. Can actually handle an
...
impressive amount of resolution and voxel space for 0 optimization!

that was a pain. Got it working on windows again. MSVC was being really
...
picky about a few errors. Good thing though, I'm not really sure why
clang + osx let me be that lax with memory

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,
but holy hell it works!

Refactored the cl init stuff, added the rest of the image handling in.
...
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?

Ah, I'm a dummy. Forgot to initialize the command queue! No wonder why it

was invalid...

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 quick printout of the hardware info. Running into a problem choosing between platforms, going to abstract CL out into it's own class and hide all that logic

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
