mitchellhansen c1e18ce17b Fixed small error in scale when doing the downward traversal step. For some reason OpenCL has decided to start completely skipping the downward traversal loop when the jump power is equal to 1/2 dimension. What the hell?

mitchellhansen 67ec7b7785 Traversal is finally able to render coherent images, lots of artifacting. Probably logic error with traversal as opposed to math error in intersection_t's

mitchellhansen af7e0bf00b going to need to either add method of getting sub voxel position from the idx mask, or keep track of both vox and sub vox position in the DFS. Converted some logic steps in the DFS over to branchless selects
7 years ago
MitchellHansen 3c76a0729a looks like the idx checking got broken somehow
7 years ago
MitchellHansen 9ab0770bdb tweaking, fixed logic errors in the DFS vox function along with some traversal errors. Hunting down a driver crash that I somehow introduced

MitchellHansen 20f36d4eb1 lots of little tweaks, the cl is still completely broken, need to revert the oct position calc

mitchellhansen 8f6ecae4cb really bad crashing, need to debug this on a cpu only machine

mitchellhansen 8f822e14f7 Have some real bad lock ups when the oct is semi full

mitchellhansen 6650eb784d Slightly closer, for some reason the face mask has been -1 and 0 this whole time????

mitchellhansen 86bcd4f0ae Well I got something coming up, performance is worse than I was hoping, but there's a lot of optimization to go

mitchell hansen d6bdcbdeca Leaving it compiling at least, CL seems to have broken at some point on my thinkpad

MitchellHansen 40634837a9 Porting over the traversal algo to do some in situ programming. Running into some pretty bad register pressure bottlenecks. Might pivot to thinking about the multistage kernel for a bit

MitchellHansen 2519532172 committing in a broken state, we got problems with the far pointers. Acting as absolute when should be relative

MitchellHansen 87b7f60fa0 found it, wasn't handling the intersection case
7 years ago
MitchellHansen ed99716565 More optimizing, removing some dumb casts. Some are needed though when they really shouldn't be? Also somehow broke shadowing in the last few commits and never noticed D=
7 years ago
MitchellHansen c5c65474d6 ~10 FPS from moving some oct stuff to const, ~0.5 fps from adding a few more consts to initializers in the kernel

MitchellHansen 5fcf1c0e44 working on the frame controller, this might get messy
7 years ago
MitchellHansen a6e18bbb54 Generalized the way I'm handling reflections. Need to do some soul
7 years ago
MitchellHansen 9ac52aef5e Hah! Was able to get the ray redirection working, very large step in the way towards multi light, refraction, reflection, and indirect lightinggit status
7 years ago
MitchellHansen ed250d1291 Octree works out to 128x128 as is, and performance seems very promising. Traversal or octree generation fixes will be next

MitchellHansen ebce781eb3 Got the octree data to the GPU and it's traversing it, but it having some corruption issues. Endianness???

MitchellHansen 86f1622090 Some machinations on a config structure as well as a restructure on how
