		<h1>Constantes de Uso do Atributo Buffer</h1>

		<p>
			As constantes de uso podem ser usadas para fornecer uma dica à API sobre como o atributo de buffer da geometria será usado para otimizar o desempenho.
		</p>

		<h2>Exemplo de Código</h2>

		<code>
		const geometry = new THREE.BufferGeometry();
		const positionAttribute = new THREE.BufferAttribute( array, 3 , false );
		positionAttribute.setUsage( THREE.DynamicDrawUsage );
		geometry.setAttribute( 'position', positionAttribute );
		</code>

		<h2>Exemplos</h2>
		<p>[example:webgl_buffergeometry_drawrange materials / buffergeometry / drawrange ]</p>

		<h2>Uso de Geometria</h2>
		<code>
		THREE.StaticDrawUsage
		THREE.DynamicDrawUsage
		THREE.StreamDrawUsage

		THREE.StaticReadUsage
		THREE.DynamicReadUsage
		THREE.StreamReadUsage

		THREE.StaticCopyUsage
		THREE.DynamicCopyUsage
		THREE.StreamCopyUsage
		</code>

		Para obter informações mais detalhadas sobre cada uma dessas constantes, consulte a documentação [link:https://www.khronos.org/opengl/wiki/Buffer_Object#Buffer_Object_Usage OpenGL].
