🔮Sigil
Declarative 3D for Kotlin Multiplatform & Jetpack Compose. Build reactive 3D scenes using familiar Compose syntax—powered by Materia's WebGPU/Vulkan engine.Sigil bridges Compose's reactivity with Materia's high-performance 3D rendering. Use standard Compose state (mutableStateOf, animate*AsState) to drive animations and scene updates.Declarative 3D SyntaxBuild scenes with Box, Sphere, Group, and Light composables. No manual loop management or context handling required.
Reactive StateDrive animations and scene updates using standard Compose state—mutableStateOf, animate*AsState, and more.
Multiplatform ReadyJVM (Desktop) with Vulkan, Web (JS/Wasm) with WebGPU/WebGL2. Android & iOS support coming soon.
PBR MaterialsPhysically Based Rendering for realistic lighting and materials. Control metalness, roughness, and color with type-safe APIs.
Create stunning 3D scenes in just a few lines
@Composable
fun RotatingCube() {
var rotationY by remember { mutableStateOf(0f) }
MateriaCanvas(modifier = Modifier.fillMaxSize()) {
// Lighting
AmbientLight(intensity = 0.5f)
DirectionalLight(position = Vector3(5f, 10f, 5f))
// Objects
Group(rotation = Vector3(0f, rotationY, 0f)) {
Box(
color = 0xFF4488FF.toInt(),
metalness = 0.5f,
roughness = 0.1f
)
}
}
}
Sigil handles the scene graph, resource management, and GPU synchronization automatically. Just describe your scene and let the engine do the heavy lifting.Powered by MateriaSigil is built on top of the Materia engine, which provides modern WebGPU/Vulkan/Metal graphics backends.
