Yodaka

Yodaka is the library for to compose 3D graphics writen in PureScript. It expected that used in Kusabi editor which provides environment that compile code and execute it.

Yodaka is a subset of purescript-three. It follows structures of Object3D / Renderable class and other interfaces.

Functions

Functions which Yodaka provides. (This is a proposal that could be changed in the future..)

add

add :: forall o. Object3D o => Effect o -> Effect Unit

Takes Object3D instance and add to main scene.

Source

render

render :: forall r. Renderable r => Effect r -> Effect TargetTexture

Takes Renderable instance and add to sub scene. It will be rendered offscreen texture.

Source

sphere

sphere :: forall opt. { | opt } -> Effect Mesh

Takes option record and make sphere. Options are match to THREE.MeshStandardMaterial now.

Source

torus

torus :: forall opt. { | opt } -> Effect Mesh

As the same as sphere function but provides torus.

Source

setUniform

setUniform :: forall a r. Renderable r => String -> a -> r -> Effect r

Takes uniform's value name newValue and Renderable instance. Set uniform of material of Rendarable. sU is syntax-sugar of this function.

Source

updateUniform

updateUniform :: forall a r. Renderable r => String -> (a -> Effect a) -> r -> Effect r

Takes uniform's value name, updater funtion and Renderable instance. Updating shader uniform of material of Rendarable. once it added, timer will apply for to update uniform's value each frame. uU is syntax-sugar of this function.

Types / Classes

Rendarable

class Renderable a

This is declared not in Yodaka but purescript-three. In Three.js's context, it's similer to THREE.Mesh. It has material and geometry.

Source

RenderTarget

newtype RendererTarget = RendererTarget
 { target :: WebGLRenderTarget, scene :: Scene }

Structure of WebGLRenderTarget and its scene. (about WebGLRenderTarget, See this great article) Yodaka's render function will compose it and add to Port that shares the context with rendering view on Kusabi editor.

This list don't discribe whole of Yodaka functions. Just collected what seems important.

Next step..., Tutorial will coming soon.
