8c1f18ac70Software raycasting now works, but has some major problems / is extremely slow. Perhaps it will only be useful in debugging the kernel via emulation

de2f0ad6a1In 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

fecf8dd8eeReveting to an older build. Something on the mac build stopped my card from running it. Added camera class Added a create_buffer method Cleaned up much of the main function Added Vector4 class, ported from sf::Vector3 Various other edits2016-09-19 02:59:33 -07:00
10bc771807MBP 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.mitchellhansen2016-09-05 22:01:07 -07:00

9c99f9edd0some tweaks, switching to windows for the weekendmitchellhansen2016-09-03 17:46:48 -07:00
cf607382a9WORKING! 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!mitchellhansen2016-09-01 22:45:48 -07:00
c565d0faccRefactored 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 raycastermitchellhansen2016-09-01 21:35:08 -07:00
a7234675cbContinuing 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 matrixmitchellhansen2016-08-31 21:47:56 -07:00
11146a6551Getting 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?mitchellhansen2016-08-30 20:43:35 -07:00
0b9010b007little tweaks, tomorrow/this week will hook up the arguments and data loadingmitchellhansen2016-08-29 21:31:04 -07:00
5d9d3c4f4dAh, I'm a dummy. Forgot to initialize the command queue! No wonder why it was invalid...mitchellhansen2016-08-29 20:29:56 -07:00
c3902c2f6eAdded 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 soonmitchellhansen2016-08-29 18:51:46 -07:00
0c70c24a52Switched 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 buffersmitchellhansen2016-08-28 22:40:29 -07:00
5dea2494a0Large 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.mitchellhansen2016-08-15 00:07:30 -07:00
edd8075afbAdded 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

3c9b39f682added the final kernel create function, moved around includes Next on the plate is either, abstract the cl routine, or begin digging into creating the kernelmitchellhansen2016-08-11 21:48:37 -07:00
d2b79ceec3Added 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 codesmitchellhansen2016-08-11 21:39:06 -07:00
49817f94b7Had a linking problem in the CMakeLists, fixed. Added a test file to check for cl/gl interop support & supported cl version Finished CL setup up to the creation of the command queuemitchellhansen2016-08-11 20:25:43 -07:00
bc093ef4e4Cleaned 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 versionmitchellhansen2016-08-09 18:31:02 -07:00
bf45af9babAdded the SFML vector class. Need to extend it to have the vector operations I want Changes to be committed: modified: CMakeLists.txt modified: README.md renamed: src/Curses.h -> include/Curses.h new file: include/Vector3.h new file: src/Vector3.cppmitchellhansen2016-08-08 15:39:36 -07:00

14987e3ba7There 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 OpenCLmitchellhansen2016-08-03 22:29:31 -07:00
2b7dceee1bMoved the view plane calc to the constructor, cleaned up old code. Added / removed relevant commentsmitchellhansen2016-08-02 22:40:55 -07:00
1de9c6dd35Ahh! 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 fantasticallymitchellhansen2016-08-02 22:26:56 -07:00
d609ed695aGoing to need to get rid of the spherical cameramitchellhansen2016-08-01 23:32:25 -07:00
c3be6e2240Alright, that little change fixed some of the negative coord problems, still have some really weird warping though.mitchellhansen2016-08-01 20:29:11 -07:00

MitchellHansen
2016-07-31 17:13:16 -07:00
3deb3a2b08alright, 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
MitchellHansen
2016-07-31 17:00:18 -07:00
f1c84c85b5So 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
MitchellHansen
2016-07-31 16:31:26 -07:00
0b8cd9a194things 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
