Detailed Description

Named texture object, see WebGL API

Member Function Documentation

reconfigure()

void NamedTexture::reconfigure

(

)

indicates the underlying picel format has been modified and that the texture should be reevaluated

upload() [1/2]

void NamedTexture::upload

(

FilterPacket

pck

)

builds named texture from input filter packet

Parameters

pck	the filter packet to use as source for texture data

upload() [2/2]

void NamedTexture::upload

(

Texture

tx

)

builds named texture from EVG texture

Parameters

tx	the EVG texture to use as source for texture data

Warning

do NOT use a Texture object constructed from a FilterPacket, this will fail and throw an exception. Use upload(FilterPacket) instead

Field Documentation

nb_textures

attribute readonly unsigned long NamedTexture::nb_textures

number of underlying textures. This can be useful when doing multi-texturing to get the next texture unit slot:

nextActiveTexture = gl.TEXTURE0 + named_tx.nb_textures;

is_gl_input

attribute readonly unsigned long NamedTexture::is_gl_input

set to true if the input to this named texture is a set of one or more OpenGL textures rather than system memory data

name

attribute readonly DOMString NamedTexture::name

name of the texture, as passed upon creation

pbo

attribute unsigned long NamedTexture::pbo

indicates if PBO is used for data transfer. By default named textures are created with no PBO transfer. To enable it, set this to true before the first texture upload
