|
=====================
|
|
Visualization module for meshes/point clouds/graphs.
|
|
|
|
# Example
|
|
|
|
```javascript
|
|
var createScene = require('gl-plot3d')
|
|
var createMesh = require('gl-mesh3d')
|
|
var bunny = require('bunny')
|
|
|
|
var scene = createScene()
|
|
|
|
var mesh = createMesh({
|
|
gl: scene.gl,
|
|
cells: bunny.cells,
|
|
positions: bunny.positions,
|
|
colormap: 'jet'
|
|
})
|
|
|
|
scene.add(mesh)
|
|
```

|
# Install
|
|
|
|
```
|
|
npm i gl-mesh3d
|
|
```
|
|
|
|
# Basic interface
|
|
|
|
## Constructor
|
|
|
|
#### `var mesh = require('gl-mesh3d')(params)`
|
|
Creates a simplicial complex that can be drawn directly in a WebGL context.
|
|
|
|
* `params` is an object that has the following properties:
|
|
|
|
+ `gl` A reference to the WebGL context
|
|
+ `cells` *(Required)* An indexed list of vertices, edges and/or faces.
|
|
+ `positions` *(Required)* An array of positions for the mesh, encoded as arrays
|
|
+ `vertexColors` A list of per vertex color attributes encoded as length 3 rgb arrays
|
|
+ `vertexUVs`
|
|
+ `cellUVs`
|
|
+ `vertexIntensity`
|
|
+ `colormap`
|
|
+ `vertexIntensityBounds` intensity range for the colormap
|
|
+ `cellIntensity`
|
|
+ `cellColors` A list of per cell color attributes
|
|
+ `meshColor` A constant color for the entire mesh
|
|
+ `vertexNormals` An array of per vertex normals
|
|
+ `cellNormals` An array of per cell normals
|
|
+ `useFacetNormals` A flag which if set to `true` forces `cellNormals` to be computed
|
|
+ `pointSizes` An array of point sizes
|
|
+ `pointSize` A single point size float
|
|
+ `ambientLight` ambient light color * intensity
|
|
+ `diffuseLight` diffuse light color * intensity
|
|
+ `specularLight` specular light color
|
|
+ `lightPosition` location of light
|
|
+ `roughness` surface roughness
|
|
+ `fresnel` surface glossiness/"rim light" factor
|
|
+ `opacity` surface opacity
|
|
|
|
**Returns** A renderable mesh object
|
|
|
|
## Update
|
|
|
|
#### `mesh.update(params)`
|
|
Updates the contents of the simplicial complex in place.
|
|
|
|
* `params` is a list of parameters which are in the same format as the constructor
|
|
|
|
## Properties
|
|
|
|
#### `mesh.lightPosition`
|
|
The 3D position of the directional light source
|
|
|
|
#### `mesh.ambientLight`
|
|
Ambient light color
|
|
|
|
#### `mesh.diffuseLight`
|
|
Diffuse light color
|
|
|
|
#### `mesh.specularLight`
|
|
Specular light color
|
|
|
|
#### `mesh.roughness`
|
|
Mesh surface roughness
|
|
|
|
#### `mesh.fresnel`
|
|
Fresnel parameter
|
|
|
|
#### `mesh.vertexNormalsEpsilon`
|
|
Epsilon for vertex normals calculation
|
|
|
|
#### `mesh.faceNormalsEpsilon`
|
|
Epsilon for face normals calculation
|
|
|
|
#### `mesh.opacity`
|
|
Opacity
