Re: Does the Geometry Shader not accept definable uniforms?

I've been attempting to reduce the amount of input that gets sent to the vertex shader by having the geometry shader handle generating vertices that are a set distance from the single vertex input through the use of uniforms. When using a uniform constant set from within the shader, it works fine, ...

Re: V/G shader to properly generate rectangle from 1-2 verti

Ok, I believe I got the calculations for positioning correct. In much the same way I had to calculate the right affine matrix (by getting it's inverse), I sorta did the reverse on calculating the position. Now I can work on figuring out which tiles are to be rendered, which if I've thought this out ...

Re: V/G shader to properly generate rectangle from 1-2 verti

Yeah, I started to see that as I kept trying and trying. I resorted to throwing in 4 vertices (and figured out why it wasn't working before). I understand that there may be problems with per-scanline sets, but I'll tackle that when I get to it. First I want to get full-screen, unmodified-scanline Mo...

V/G shader to properly generate rectangle from 1-2 vertices

Before I start, I want to say that I'm doing this to help StapleButter with BlargSNES. I'm attempting to develop a routine for displaying Mode7 using GPU acceleration, as it currently is handled via software-rendering (which is slow). What I'm looking to do is take either 1 or 2 vertices I input, an...

I was wondering that too. Says I don't have permissions to read that forum, yet I can log out and read it. Was hoping to ask a question regarding shaders, but I can't (at least not there).

Re: devkitARM release 44 and libraries

Went and re-installed devkitpro, but it seems Avast is identifying false positives, preventing various parts of the installation from being installed/written (like bin2s within devkitARM), so I had to uninstall that and go with another free anti-virus program. Trying out Panda. At least it doesn't g...

Re: Question about possible ADPCM streaming

An update. I have stereo ADPCM streaming working. I tweaked the asm code and stream-loading code, so the audio should be a bit more fluid. Clicks and popping that remain are probably due to timing issues when dealing with the format ADPCM is enclosed in ('1' 32-bit header + 'n' 4-bit data samples in...

Re: Question about possible ADPCM streaming

Well, I decided that if I wanted to see if it were possible, then I'd try it myself. I looked into the IMA-ADPCM format specifically used by Microsoft in their WAVE format, and I found something quite convenient. The format that Microsoft IMA-ADPCM data is stored is based on sequential block chunks,...

Question about possible ADPCM streaming

If I understand the way Maxmod works, ADPCM cannot be streamed because streaming uses a ring-buffer, which would interfere with how ADPCM audio is played (which is having an initial sample and table index, followed by 4-bit values that contribute to the decoding process to 16-bit samples). My questi...
