jagenjo / rendeer.js Goto Github PK

In rendeer.js source code, I found multiple ways to set uniforms for SceneNode, all used in the renderNode function in RD.Renderer. These are node._uniforms, node.onShaderUniforms and renderer.onNodeShaderUniforms. But these are not used/called when any material is set on the node.
Is this intentional and is there any other way to set SceneNode specific uniforms?

You can't stop orbiting once it starts - ESC doesn't help

Have you thought about publishing rendeer.js to NPM registry? Looks like you'd only need package.json, plus perhaps a tag or two. LiteGL is there already (https://www.npmjs.com/package/litegl/v/0.0.2) though not sure which version - I don't see the corresponding tag in Github). It would make it much easier to consumer rendeer.js for downstream projects.

Hello Javi,

If we have a node (SceneNode), and it has many descendants (a sub tree), what should happen when we apply opacity with a value less than 1 to it?

1. It, and all of it's children should become transparent, multiplying opacities down the scene graph.
2. It's content should become transparent but not that of its descendants.
3. Same as (1), but the whole object should be flattened into a plane.

The reason I want your opinion is because the new specs for CSS 3D (css-transforms) state here that the answer is (3).

To see what I mean, view these two examples in Chrome 53 or higher:

• https://jsfiddle.net/trusktr/ymonmo70/16
• https://jsfiddle.net/trusktr/ymonmo70/17

The second example has opacity applied to the node that contains all the sub-nodes which compose the car. The opacity, according to spec, flattens the car into a plane (turns it into paper!).

I'm asking various 3D engine authors for opinions of what the correct or most expected behavior should be.

All the best,
~ Joe
