Opengl texture2d function

WebOpenGL provides a number of functions for accessing images through image variables. Image operations have "image coordinates", which serve the purpose of specifying where in an image that an access should take place. Image coordinates are different from texture coordinates in that image coordinates are always signed integers in texel space. WebThe basic scalar type constructors can be used to convert values from one type to another. What you get depends on the kind of conversion. from bool. If it is false, then you get 0, in whatever the output type is (floating-point types get 0.0). If it is true, then you get 1, in whatever the output type is. to bool.
