Constructor
new Attribute(buffer, sizeopt, offsetopt, normalizedopt)
| Name | Type | Attributes | Default | Description |
|---|---|---|---|---|
buffer | Buffer | The Buffer instance passed in the constructor. | ||
size | number | <optional> | buffer.stride | The number of values of the array that should be associated with a particular vertex. For instance, if this attribute is storing a 3-component vector (such as a position, normal, or color), then size should be 3. |
offset | number | <optional> | 0 | The offset in the underlying array buffer where an item starts. |
normalized | boolean | <optional> | false | Indicates how the underlying data in the buffer maps to the values in the GLSL shader code. |
