At this point, the UI renders in the browser through WebGL, with no GL errors. Progress towards #446 🕸️ Web support * main: enable render loop on wasm, disable events_loop on wasm for now Allow for testing rendering on WebGL * chunk_builder: disable on wasm due to no threads on wasm Chunks will not be correctly rendered, but other parts of the program now can be tested instead of crashing in std::thread * chunk_frag: glBindFragDataLocation is only on native, WebGL 2 uses in-shader specification layout(location=), which works on native in OpenGL 4.1 but we're on OpenGL 3.2 - see https://www.khronos.org/opengl/wiki/Fragment_Shader#Output_buffers * std_or_web: always fail File::open() to avoid servers.json empty string JSON parse failing * www: update installation instructions * render: fix apparent TEXTURE_MAX_LEVEL -> TEXTURE_MAG_FILTER typo * render: correct type for internalFormat DEPTH_COMPONENT24 Valid combinations of format, type, and internalFormat are listed at https://www.khronos.org/registry/OpenGL/specs/es/3.0/es_spec_3.0.pdf#page=124&zoom=100,168,206. We had UNSIGNED_BYTE for DEPTH_COMPONENT24, but only UNSIGNED_INT is a valid type for this internal format. Fixes texImage: Mismatched internalFormat and format/type: 0x81a6 and 0x1902/0x1401 and fixes the subsequent GL_FRAMEBUFFER_INCOMPLETE_ATTACHMENT error. * render: gl::MULTISAMPLE (0x809d) is not available on WebGL Fixes WebGL warning: enabled: cap: Invalid enum value <enum 0x809d> 0.bootstrap.js line 11 > eval:851:21 * gl: replace set_float_multi_raw with a safer set_float_multi Removes use of passing raw pointers in set_float_multi_raw parameters Instead, casts raw pointers to flatten, similar to set_matrix_multi Fixes uniform setter: (uniform colorMul[0]) values length (1) must be a positive integer multiple of size of <enum 0x8b52>. * render: model: send BYTE to id attrib, fixes type mismatch Fixes drawElementsInstanced: Vertex attrib 0 requires data of type INT, but is being supplied with type UINT |

stevenarella-web
Web app for running Stevenarella as WebAssembly
Status: very incomplete. It currently compiles but does not run, due to required modifications to adapt to the web, for progress see: 🕸️ Web support
Building
To build for wasm32-unknown-unknown, run in the top-level directory (not www):
rustup target add wasm32-unknown-unknown
cargo install wasm-bindgen-cli
cargo install wasm-pack
wasm-pack build --dev
or:
cargo web start --target wasm32-unknown-unknown
Running
After building the Rust app, run the NodeJS web server as follows:
cd pkg
sudo npm link
cd ..
cd www
npm link stevenarella
npm install
npm start
open http://localhost:8080/
Credits
Based on rustwasm/create-wasm-app:
An
npm inittemplate for kick starting a project that uses NPM packages containing Rust-generated WebAssembly and bundles them with Webpack.
