@mkeeter thank you for publishing this paper and code. On your "future work" slide, you mentioned blackbox oracle support. Would oracle just be a custom shader that bypasses interval evaluation and tape shortening?

Hi Matt. First of all, impressive work you're doing here :)

I suspect that performance could be improved considerably if each opcode was 32bit instead of 64bit. It seems like the reason they're 64bit is to encode immediate floats or jump positions. What about switching to 32bit opcodes and when an immediate value is expected, the interpreter steps one word forward and reads the immediate at that location, before continuing with the interpreter loop as usual?

I might try this out soon, but until then this issue can be a place for discussion..

When cloning the repository with all submodules, I get the following error:

Is the intention to use a git account with a username "git"? Or is there a typical use case I'm unaware of?

Running the following commands on a fork allowed me to pull the submodule without errors:

git config submodule.libfive.url https://github.com/libfive/libfive

git submodule update --recursive --remote

I would make a PR but this modifies .git/config and I'm unsure if/how those sorts of changes can be merged. There also might be another step necessary to push the results to the remote, I'm not sure.

Really nice paper by the way, I'm excited to try out the technique 🙂

Hello! Thanks for your excellent work. I don't know much about your research, but I'm very interested in that. I tried for two days and finally managed to compile and run the code you provided. However, I got stuck in using the gui demo. I compiled and got the 'demo' file. When I run it, I got:

Error: unknown error ../gui/tex.cu 29

which corresponds to the source code

cudaGraphicsResource* register_texture(GLuint t)
{
    cudaGraphicsResource* gl_tex;
    CUDA_CHECK(cudaGraphicsGLRegisterImage(&gl_tex, t, GL_TEXTURE_2D,
                                      cudaGraphicsMapFlagsWriteDiscard)); // this line
    return gl_tex;
}

I tried to delete the function CUDA_CHECK( ) and successfully opened the gui window! But it seems to be all black and no any model. Is this because I deleted that function? What should I do next?
