ANGLE_instanced_arrays

The ANGLE_instanced_arrays extension is part of the WebGL API and allows to draw the same object, or groups of similar objects multiple times, if they share the same vertex data, primitive count and type.

Methods

drawArraysInstancedANGLE()

drawArraysInstancedANGLE(
   mode, 
   first, 
   count, 
   primcount
): void;

The ANGLE_instanced_arrays.drawArraysInstancedANGLE() method of the WebGL API renders primitives from array data like the gl.drawArrays() method. In addition, it can execute multiple instances of the range of elements.

primcount	number

Returns

void

drawElementsInstancedANGLE()

drawElementsInstancedANGLE(
   mode, 
   count, 
   type, 
   offset, 
   primcount
): void;

The ANGLE_instanced_arrays.drawElementsInstancedANGLE() method of the WebGL API renders primitives from array data like the gl.drawElements() method. In addition, it can execute multiple instances of a set of elements.

offset	number
primcount	number

Returns

void

vertexAttribDivisorANGLE()

vertexAttribDivisorANGLE(index, divisor): void;

The ANGLE_instanced_arrays.vertexAttribDivisorANGLE() method of the WebGL API modifies the rate at which generic vertex attributes advance when rendering multiple instances of primitives with ext.drawArraysInstancedANGLE() and ext.drawElementsInstancedANGLE().

Parameters

Parameter	Type
index	number
