GitLab now enforces expiry dates on tokens that originally had no set expiration date. Those tokens were given an expiration date of one year later. Please review your personal access tokens, project access tokens, and group access tokens to ensure you are aware of upcoming expirations. Administrators of GitLab can find more information on how to identify and mitigate interruption in our documentation.

alfrh02 authored 3 months ago

+ added gradient check before light calculation;
+ circles now indicate where lights are located when in lighting mode;
+ added controls section to README;
+ added tool icon in lower-left for better usability;
* renamed light.size to light.radius for clarity;
* organised lighting.frag into functions;
* changed to use 'out vec4 fragColor' rather than deprecated gl_FragColor;
- removed uApple & uSmoothShadows shader uniforms (no more manual toggling of soft/hard shadows);

Radiance Cascades Demo

Requirements
Setup (macOS, Linux)
Setup (Windows)
Controls

2D lighting demo. Intended for 1080p displays.

Maze image texture initially generated via mazegenerator.net.

Requirements

CMake 3.25
- A C++11 (or higher) compiler
Raylib 5.5 (provided via CMake if not installed system-wide)
- If Raylib is not installed on your machine, CMake will download and build Raylib for you in the build directory.

This currently builds and runs on macOS, Arch Linux (on X11), and Windows. No planned support for Wayland :P

Setup (macOS, Linux)

# run the convenience build script
./build.sh    # to build without running
./build.sh -r # to build and run the resulting binary

# or build it manually via CMake
mkdir build
cd build
cmake ..
make
cd .. # run the resulting binary in the source directory, not the build directory
./radiance_cascades

Setup (Windows Visual Studio)

Via command prompt:

mkdir build
cd build
cmake ..

This will generate a VS solution file (.sln) for you to use for compilation.

Make sure to run any resulting .exe from the project root directory.

Controls

1, 2, & 3 toggles between drawing, lighting, and viewing mode.

Scrolling up or down increase brush/light size depending on if you are in drawing or lighting mode.

C clears the canvas if in drawing mode, and removes all lights if in lighting mode.

R resets the canvas to the original maze layout if in drawing mode, and resets to the starting lights if in lighting mode.

F3 to open the debug UI. When the debug UI is open, scrolling the mouse will change the amount of shadow cascades.

Left-mouse-button erases in drawing mode, or deletes nearby lights when in lighting mode.

Right-mouse-button draws in drawing mode, or places a light when in lighting mode.

Middle-mouse-button can be used to move lights around in any mode.
