Features

• Add clay.InstancedMesh. Usage:

var instancedMesh = new clay.InstancedMesh({
  geometry: geometry, material: material
});
for (var i = 0; i < 100; i++) {
    var instanceNode = new clay.Node();
    instanceNode.position.set(i - 50, 0, 0);
    instanceNode.update();
    instancedMesh.instances.push({ node: instanceNode });
}
scene.add(instancedMesh);

Enhancements

• Support base64 decode of buffer in glTF loader.

• Add transform decompose when creating OrbitControl

• Better compatibility on weapp platform

Bugfixes

• Fix skybox with orthographic camera

• Fix uv repeat and uv offset in preZ pass and shadow pass.

fbx2gltf

• Add vertex color support by @xAlien95

• Better support for other platforms like wechat.

• Fix damping in OrbitControl not work.

Features

• Add normalScale in clay.standard shader. by @SamuelTS

• Implement plugin.GamepadControl. by @SamuelTS

• App3D#createMaterial add textureLoaded and texturesReady callback in parameter object.

Enhancements

• More robust #define parsing in shader.

• [fbx2gltf] works in python2.7 by @fmmoret . See #80

• Improve velocity buffer of skinned mesh.

Enhancements

• Separate submodules in g-lmatrix. Abstraction of GeometryBase. Reduced core bundled size to 22k(gzipped). See https://github.com/pissang/claygl#minimum-bundle-example

• Adjust panorama texture orient.

Bug fixes

• Fix finger rotate bug on mobile.

This version is about to fix the build in 1.1.3

Enhancements

• Reduced the minimum bundled size from 38k to 28k. Here is a minimum example code:

import { Renderer, Geometry, Shader, Material } from 'claygl';
const renderer = new Renderer({
    canvas: document.getElementById('main')
});
const geometry = new Geometry();
// Add triangle vertices to position attribute.
geometry.attributes.position.fromArray([
    [-0.5, -0.5, 0],
    [0.5, -0.5, 0],
    [0, 0.5, 0]
]);
const material = new Material({
    shader: new Shader(vsCode, fsCode)
});
renderer.renderPass([{ geometry, material }]);

• Skybox support 2D panorama environment map. Skydome is DEPCRATED.

• Add occlusionMap in clay.standard shader. Also support occlusionTexture in glTF Loader.

• Use vertex texture to store skin matrices to support devices with limited uniforms number.

• Compatible with browsers don't support EXT_shader_texture_lod extension.

Bug Fixes

• Fix tree shaking in webpack 4.0 may cause builtin shader lost.

• Fix velocity buffer may be wrong.

New Features

• [GBuffer] Add velocity buffer for usage of motion blur and temporal reprojection. Use GBuffer#enableTargetTexture4 to enable rendering of velocity buffer, use GBuffer#getTargetTexture4 to get the buffer. In the shader code velocity can be extracted like following:

vec4 texel = texture2D(velocityTex, v_Texcoord); 
// If texel has valid velocity info
if (texel.a > 0.0) {
  vec2 vel = texel.rg * 2.0 - 1.0;
}

Enhancements

• Support alphaCutoff in prez pass and shadow map pass.

• App3D#loadModel and App3D#createMaterial add textureConvertToPOT property in the config.

• application.create add autoRender config.

• application.create add methods config. And these methods can be called outside using app.methods.xxxx.

• Add App3D#render method.

• Add App3D#height and App3D#width

• Vector3 builtin values like Vector3.ZERO will always create a new value.

Bug Fixes

• Fix image based lighting wrong when roughness is near to 1.

• Fix lighting bug in deferred rendering.

• Fix GBuffer#dispose does not work bug.

• Use blank texture when texture value is not renderable or is null. Remove the warnings.

Breaking Changes

• All the modules under math have been moved to root for more short reference. For example, clay.math.Vector3 now is clay.Vector3. For now clay.math.Vector can still work but not suggested.

• Move clay.animation.Timeline to clay.Timeline. For now clay.animation.Timeline can still work but not suggested.

• Move clay.compositor.createCompositor to clay.createCompositor. For now clay.compositor.createCompositor can still work but not suggested.

• clay.util.mesh.splitJoints will use the material of input mesh. Not clone a new one for each new-created mesh.

• Remove Renderable#lineWidth

New Features

• Add typescript declarations. See https://github.com/pissang/claygl/tree/master/typescript

• [Texture2D] Add convertToPOT property.

• Add sideEffects in package.json to support tree shaking in webpack4.0

Bug Fixes

• Fix disposeTexture parameter not work in Scene#disposeNode

• [OrbitControl] Fix dragging will not be stopped when the mouse is out of the viewport.

• [OrbitControl] Disable the right mouse button.

Enhancements

• Improve shader parser, support uniform initialization value and multiple declaration in one line. Now code like following can be parsed and extrated uniforms correctly

uniform vec3 color = vec3(0.0, 0.0, 0.0), opacity = 1.0;

• Performance improvements for the large scenes. Can be up to 50% in the scene of 10k objects.

• [OrbitControl] Optimize the dragging when mouse events are triggered more frequently than animation frame.

• [PBR] 4x faster cubemap prefiltering

Enhancements

• App3D#createCamera add extent parameter when camera type is orthographic

• Add App3D#cloneNode for cloning skinned models with proper skeleton handling. See example Dancing Group

• Use indices type instead of vertex count to determine if use OES_element_index_uint extension

Bugfixes

• Fix scene light numbers can't change bug

• Fix directional light with shadowCascade will throw error.
