ToodeeSculpt

Combine 2d sdf primitives with smooth operator to sculpt your shape

• the editor

• same shader exported in shadertoy

Features

• Primitives : disc, triangle, oriented box, ellipse, pie, arc, spline, capsule
• Primitive can be rounded, rendered with outline
• Boolean operator : union, substraction, smooth blend
• Intuitive editor, undo support, grid snapping, copy/paste, rotation, scaling
• Load/save, export to shadertoy

Specialized SDF renderer

• Everything is rendered with just one drawcall
• Primitives are binned per tile on the GPU, you don't pay the cost of far away primitives (as you do with your typical shadertoy shader)
• Pixels are written once, alpha blending is done in the shader (a.k.a free alpha blending)
• Anti-aliasing based on sdf

Find more details in the the documentation of the renderer

Next steps

• Primitive animation
• More export options (PNG, sprite for in-house engine)
• Better user experience
• More primitives, more options

How to build

Prerequisite

• a macOS dev environment (xcode tools)
• glfw (brew install glfw)
• cmake

Compilation

• open a terminal in the folder
• mkdir build
• cd build
• cmake -DCMAKE_BUILD_TYPE=Release ..
• cmake --build .
• ./ToodeeSculpt

It only has been tested on a M2 Max studio and a M1 Pro mac bookpro running macOS 14.x Currently, there is no plan to support another platform.
