Representation → BufferRepresentation

Representation for showing buffer objects. Good for efficiently showing large amounts of geometric primitives e.g. spheres via SphereBuffer. Smaller numbers of geometric primitives are more easily shown with help from the Shape class.

Name: buffer

Example:

// add a single red sphere from a buffer to a shape instance
var shape = new NGL.Shape( "shape" );
var sphereBuffer = new NGL.SphereBuffer( {
    position: new Float32Array( [ 0, 0, 0 ] ),
    color: new Float32Array( [ 1, 0, 0 ] ),
    radius: new Float32Array( [ 1 ] )
} );
shape.addBuffer( sphereBuffer );
var shapeComp = stage.addComponentFromObject( shape );
shapeComp.addRepresentation( "buffer" );

// add a single red sphere from a buffer to a structure component instance
stage.loadFile( "rcsb://1crn" ).then( function( o ){
    var sphereBuffer = new NGL.SphereBuffer( {
        position: new Float32Array( [ 0, 0, 0 ] ),
        color: new Float32Array( [ 1, 0, 0 ] ),
        radius: new Float32Array( [ 1 ] )
    } );
    o.addBufferRepresentation( sphereBuffer, { opacity: 0.5 } );
} );
