A module that draws meshes with a simple orbit based camera. This is useful for quickly making demos and live coding.
var shell = require("mesh-viewer")()
var mesh
shell.on("viewer-init", function() {
mesh = shell.createMesh(require("bunny"))
})
shell.on("gl-render", function() {
mesh.draw()
})
npm install mesh-viewer
The main viewer class is a modification of gl-now
and inherits all the same properties and methods as that.
var createShell = require("mesh-viewer")
Creates a viewer. In addition to accepting all the arguments as gl-now, it also takes in the following arguments:
fov
Default fov for camerazNear
Near clip planezFar
Far clip planemeshColor
Default color for meshespointSize
Default point size for meshesuseCellNormals
If set, use flat shading for polygonsambient
Default ambient light color * intensitydiffuse
Default diffuse light color * intensityspecular
Default specular light color * intensityspecularExponent
Default specular exponentlightPosition
Default light position
Returns A mesh viewer shell
In addition to the events in gl-now
and game-shell
, mesh-viewer
has the following event:
This event is triggered after the viewer is initialized.
An instance of a game-shell-orbit-camera
that controls the viewing direction.
The FOV of the camera
The near z clip plane distance
The far z clip plane distance
Creates a mesh object that can be drawn. This works the same as gl-simplicial-complex
. The params
object accepts the following parameters:
cells
(Required) An indexed list of vertices, edges and/or faces.positions
(Required) An array of positions for the mesh, encoded as arraysvertexColors
A list of per vertex color attributes encoded as length 3 rgb arrayscellColors
A list of per cell color attributesmeshColor
A constant color for the entire meshvertexNormals
An array of per vertex normalscellNormals
An array of per cell normalsuseFacetNormals
A flag which if set to true forces cellNormals to be computedpointSizes
An array of point sizespointSize
A single point size float
Returns A drawable mesh object
Draws the mesh object. Params has the same properties as in gl-simplicial-complex
Updates the mesh. Same conventions as before.
Destroys mesh releasing all resources.
