* Add the base of the example. May need refining and definitely fact-checking. * Start change to changelog. * Complete changelog change for repeated-compute. * Apply suggestion to fix typos. Co-authored-by: Alphyr <47725341+a1phyr@users.noreply.github.com> * Add storage-texture example which currently works native but needs to be changed to work for wasm. [no ci] * repeated-compute now works on the web. [no ci] * `storage-texture` now works on the web as well as native. * Format because I forgot to do that (ugh). * Add `storage-texture` to changelog. * Add `render-to-texture` example. * Not all the files got git added. Fixed it. * Add `render-to-texture` to changelog. * Make better readme's and add examples to said readme's. * Oops. Put the example updates in the wrong place. * Add `uniform-values` example. * Apply clippy suggestions. * Improved readme's and documentation. * Fmt. Turning into the Joker rn. * Make instructions for examples on the web more clear. \(Fmt and clippy happy\) * hello-workgroups It doesn't work. * Add basic comments and readme to hello-workgroups. * Add hello-synchronization example. Currently doesn't have any tests but those should be added later. * Forgot to check wasm compatibility for hello-synchronization. Fixed it. * Add test for hello-synchronization. * Make my examples downlevel defaults. * Make uniform-values downlevel defaults. (Forgot to do that last commit.) * Fix clippy doc complaints. * Didn't fully fix the docs last commit. Got it here I think. * Fix redundant bullet point in examples/hello-workgroups/README.md. * Trim down the introduction section of examples/hello-workgroups/README.md. * Add technical links section to examples/hello-workgroups/README.md. * Use idiomatic Rust comments, break up big text wall into paragraphs, and fix some spelling errors. * Move output image functions into examples/common and give output_image_wasm some upgrades. * Modify changelog for moving output_image_native and output_image_wasm into wgpu-example. * Fix output_image_wasm. (Formerly did not handle pre-existing output image targets.) * Make a multiline comment be made of single lines to be more ideomatic. * "Fix" more multiline comments. I think this is actually the last of them. * Make the window a consistant, square size that's convenient for viewing. * Make the window on uniform-values not endlessly poll, taking up 100% of the main thread in background at idle. Also, change layout a little and make native use nanos by default for logging. * Make execute in hello-synchronization return a struct of vecs instead of using out parameters. * Didn't realize the naming of wgpu_example::framework so I moved my common example utility functions into wgpu_example::utils. * Add add_web_nothing_to_see_msg function to replace all the instances of adding "open the console" messages across the examples. * Add small documentation to add_web_nothing_to_see_msg and change it to use h1 instead of p. * Add documentation to output_image_native and output_image_wasm in examples/common. * Do better logging for output image functions in wgpu-example::utils. * Remove redundant append_child'ing of the output image element in wgpu-example::utils::output_image_wasm. * Fix error regarding log message for having written the image in wgpu-example::utils::output_image_native. * Fmt. * In examples/README.md, re-arrange the examples in the graph to be in alphabetical order. * Fix changlog item regarding wgpu-example::utils and the output image functions. * Move all the added examples into one changelog item that lists all of them. * Updated table in examples/README.md with new examples. Added new features to the table to accurately represent the examples.\n\nFor the new features, not all old examples may be fully represented. * Fix inaccurate comment in hello-workgroups/src/shader.wgsl. * Update examples/README.md to include basic descriptions of the basic examples as well as hints on how examples build off of each other. * Remove `capture` example. See changelog entry for reasoning. * Fix typo in hello-workgroups/shader.wgsl * Change the method of vertex generation in the shader code of render-to-texture to make it more clear. * Modify/correct message in repeated-compute/main.rs regarding the output staging buffer. * Update message in uniform-values/main.rs about writing the app state struct to the input WGSL buffer. * Add notice in repeated-compute/main.rs about why async channels are necessary (portability to WASM). * Revise comment in uniform-values/main.rs about why we don't cast the struct using POD to be more clear. * Change uniform-values to use encase for translating AppState to WGSL bytes. * Cargo & Clippy: My two best friends. * Add MIT-0 to the list of allowed liscences. * Fix docs for wasm. --------- Co-authored-by: Alphyr <47725341+a1phyr@users.noreply.github.com> |

uniform-values
Creates a window which displays a grayscale render of the Mandelbrot set. Pressing the arrow keys will translate the set and scrolling the mouse wheel will zoom in and out. If the image appears too 'bright', it may be because you are using too few iterations or 'samples'. Use U and D to increase or decrease respectively the max number of iterations used. Make sure to play around with this too to get an optimally photogenic screen cap. The window can be resized and pressing ESC will close the window. Explore the Mandelbrot set using the power of uniform variables to transfer state from the main program to the shader!
Usage of Uniform Buffers / Variables
Since the codebase of this example is so large (because why not demonstrate with a sort-of game) and the points of interest in terms of the actual point of the example so small, there is a module doc comment at the top of main.rs that points out the important points of the usage of uniform values.
Limitations
At some point in exploring the fractal, you may discover there is actually a resolution; if you zoom to deep, things become weirdly pixilated. Unfortunately, the relatively basic shader is currently limited by the faults of 32-bit floating point precision. As much as I'd like to upgrade to 64-bit floats, the support in WGSL for f64's is limited and you can't even cast to one as of time of writing. Still pretty cool though.
