Parameters

VariablesDescription
target
Specifies the symbolic name of the target texture, one of GL_TEXTURE_1D , GL_TEXTURE_2D , GL_TEXTURE_3D , GL_TEXTURE_1D_ARRAY , GL_TEXTURE_2D_ARRAY , GL_TEXTURE_RECTANGLE , GL_TEXTURE_2D_MULTISAMPLE , GL_TEXTURE_2D_MULTISAMPLE_ARRAY , GL_TEXTURE_CUBE_MAP_POSITIVE_X , GL_TEXTURE_CUBE_MAP_NEGATIVE_X , GL_TEXTURE_CUBE_MAP_POSITIVE_Y , GL_TEXTURE_CUBE_MAP_NEGATIVE_Y , GL_TEXTURE_CUBE_MAP_POSITIVE_Z , GL_TEXTURE_CUBE_MAP_NEGATIVE_Z , GL_PROXY_TEXTURE_1D , GL_PROXY_TEXTURE_2D , GL_PROXY_TEXTURE_3D , GL_PROXY_TEXTURE_1D_ARRAY , GL_PROXY_TEXTURE_2D_ARRAY , GL_PROXY_TEXTURE_RECTANGLE , GL_PROXY_TEXTURE_2D_MULTISAMPLE , GL_PROXY_TEXTURE_2D_MULTISAMPLE_ARRAY , GL_PROXY_TEXTURE_CUBE_MAP , or GL_TEXTURE_BUFFER .
level
