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

A decent ways towards getting the octree built. Small snag in the way fully valid or invalid non-leafs are handled

Got some geometry up and rotating. It will be pretty trivial to pass in

the camera rotation now and have it follow along.

Modified CMake to now find and link GLEW

Slight tweaks to how CMake interacts with VS
Added small OpenGL testing class which draws over the raycasted image
Going to use Gl to start helping with debug / enabling hybrid rendering

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

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

A good portion of the fallback software caster is done.

Need to test, add global lighting, add switch

The new rendering method now works on the full compat case.

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
2016-10-06 23:25:31 -07:00

Added a 1/4 working phong shading function, breaks when the light
...
direction in in negative values. The normals of voxels also are
symmetrical which needs to be fixed.

Tweaked indexing, there is a discrepancy at z_max values that I need to

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

Also fixed the distortion around the XY axes

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
2016-09-03 19:23:50 -07:00
cf607382a9
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!
2016-09-01 22:45:48 -07:00
a7234675cb
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
2016-08-31 21:47:56 -07:00
c3902c2f6e
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
2016-08-29 18:51:46 -07:00
0c70c24a52
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
2016-08-28 22:40:29 -07:00
5dea2494a0
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

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

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
2016-07-31 17:00:18 -07:00

f1c84c85b5
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

things are casting now and sfml is rendering the way I want it to.
...
The voxel stepping is still all messed up, and it seems that there is
some data corruption on the map that I'll need to dig into
