Finally found the root of that off by one error. Changed up the readme.

Shadows now working, though they are still voxel based. Need to calculate where on the surface the ray hits, and then send the ray out from that point.

Working with the Blin-Phong lighting. Fixed the symmetry between the normals. Starting working on shadows

Added lookat function. Fixed various coordinate missmatches and issues. Fixed camera movement. Added some input functions. I need some way to log fps and find those hitches

Software raycasting now works, but has some major problems / is extremely

slow. Perhaps it will only be useful in debugging the kernel via emulation

Added a kernel to help test opencl data passing
renamed the kernels, buffers, etc.

In the middle of a couple of things right now, but decided to focus a

little bit less on the lighting and start laying groundwork for the SVO
The map section was in real need of some love so I deleted a bunch of
stuff and started prototyping the pointer arithmetic that I need to do

symmetrical which needs to be fixed.

sort out. Added some 2d optimization functions for fun, currently doing a
class involving them

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.

that was a pain. Got it working on windows again. MSVC was being really

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
