For others to get node’s mesh size function getNodeMeshSize(node) { const halfExtents = node.getComponent(MeshRenderer).model.modelBounds.halfExtents; Thanks so much! That’s the code I need! model.modelBounds.halfExtents; return halfExtents.clone().multiplyScalar(2); multiplyScalar(2); }

Today, I had the pleasure to interview Ian Deane, the developer behind Mesh Baker. This famous Unity asset lets you drastically reduce your draw calls so your game runs at substantially higher frame-rate. Let's see what he has to say.

I created custom mesh let mesh = cc.utils.createMesh({ positions : positions, indices : indices, doubleSided : true }); and i would like a make color of every triangle with different color as on picture below How could I achieve it ? right now Mesh uses color from Material and mesh filled with one color.

Introduction and index of this series is here. The previous post investigated some lossless filtering of data, before passing it to a regular compression library. Our result so far is: 94.5MB of data can get filtered+compressed down to 23.0MB in one second (split/shuffle bytes, delta encode, zstd or kraken compression).

Hi, I’m trying to use a simple 3d model (with a cube-mesh & material of effect “bultin-standard”) as basic object to be emitted in particleSystem My approach was to set “Render>RenderMode” to “Mesh” and fill the “Mesh” & “CPU Material” as I wanted The problem is the material won’t let me replace it if new material doesn’t use effect as (..)

Hello there, I have made a weapon stick to a user’s hand, using the ‘sockets’ property on skeletalanimation component. I’m wondering is there a way to add a constant rotation transform to this newly created socket. Want to rotate this axe -90 degrees on Z axis so the player is weilding it correctly.

You can try this solution by mounting an empty node on the weapon node hierarchy and then setting the rotation on this node.

colors is the number array so I feel you should push RGB values separately, You can try replacing colors.push( color ); colors.push( color); colors.push( color); with colors.push(color.r, color.b); Also be sure you have ticked the USE VERTEX COLOR property for the material.

Here are the implementation of water wave effects on 2D sprites and 3D meshes: Preview Link The math behind it is simple, the water wave is simulated by the Sin function, and then the fluctuation range is increased in the Update function. Use the water wave effect on the 3D meshes This is only for 3D planes with tiled UV Mapping.

Analysis The whole effect can be split into two parts, one for the simulation of the mesh and one for the rendering of the mesh. No need to define the vertex format, and even Cocos has support for sprite meshes. Well, it’s very comfortable, much more comfortable than just a mesh, and it has some practicality too.

Firstly, Sprite is a quad, the mesh is static for easier usage. You can have a custom render component and make its mesh with multiple quad, but it really isn’t necessary. You can achieve gradient color within one quad. Just calculate color step in the fragment shader is enough.
