ProgramFragment

Class Overview

The Renderscript fragment program, also known as fragment shader is responsible for manipulating pixel data in a user defined way. It's constructed from a GLSL shader string containing the program body, textures inputs, and a Type object that describes the constants used by the program. Similar to the vertex programs, when an allocation with constant input values is bound to the shader, its values are sent to the graphics program automatically.

The values inside the allocation are not explicitly tracked. If they change between two draw calls using the same program object, the runtime needs to be notified of that change by calling rsgAllocationSyncAll so it could send the new values to hardware. Communication between the vertex and fragment programs is handled internally in the GLSL code. For example, if the fragment program is expecting a varying input called varTex0, the GLSL code inside the program vertex must provide it.

Summary

[Expand] Inherited Methods
From class android.renderscript.Program void bindConstants(Allocation a, int slot) Binds a constant buffer to be used as uniform inputs to the program void bindSampler(Sampler vs, int slot) Binds an object that describes how a texture at the corresponding location is sampled void bindTexture(Allocation va, int slot) Binds a texture to be used in the program synchronized void destroy() destroy disconnects the object from the native object effectivly rendering this java object dead. void finalize() Called before the object's memory is reclaimed by the VM. void setName(String name) setName assigns a name to an object.
From class java.lang.Object Object clone() Creates and returns a copy of this Object. boolean equals(Object o) Compares this instance with the specified object and indicates if they are equal. void finalize() Called before the object's memory is reclaimed by the VM. final Class<?> getClass() Returns the unique instance of Class that represents this object's class. int hashCode() Returns an integer hash code for this object. final void notify() Causes a thread which is waiting on this object's monitor (by means of calling one of the wait() methods) to be woken up. final void notifyAll() Causes all threads which are waiting on this object's monitor (by means of calling one of the wait() methods) to be woken up. String toString() Returns a string containing a concise, human-readable description of this object. final void wait() Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object. final void wait(long millis, int nanos) Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object or until the specified timeout expires. final void wait(long millis) Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object or until the specified timeout expires.
