Abstract
Aspects of the invention relate generally to enforcing elements of the OpenGL ES specification. More specifically, regardless of whether or not the underlying API system would allow NPOT textures, the systems and methods herein may disallow them. As a result, objects bound with these textures may be considered errors, non-renderable, and rendered in black. In order to accomplish this, various functions may be tracked to determine whether an NPOT texture that uses mips is being bound to an object, and if so, treat the condition as an error and bind (then draw) the object with a black texture.
Claims18
A computer-implemented method for binding textures and generating an image of an object using a graphics library including functions and elements, the method comprising:
- generating a variable to track a number of non power of two textures comprising a length dimension or a width dimension which is not a power of two, the non power of two textures being set to use mips;
- tracking the use of a first function;
- setting a value for the variable based on the use of the first function;
- receiving a request from a user to use a second function to bind one or more textures to the object and draw the object;
- when the value indicates that there are non power of two textures set to use mips, then:
- (a) identifying a plurality of textures including the one or more textures;
- (b) for each texture of the plurality of textures, determining, by one or more processors, whether the texture is an non power of two texture;
- (c) for each non power of two texture, determining whether the texture is set to use mips;
- (d) for each of the one or more textures which is an non power of two texture and set to use mips, binding a black texture to the object;
- (e) drawing the object in black;
- (f) calling the second function;
- and
- (g) after drawing the object in black, binding the one or more textures to the object.
