GLSL source for the shader program's vertex shader. This is the version of the source provided when the shader program was created, not the final source provided to WebGL, which includes Cesium bulit-ins.

Methods

destroy

Destroys the WebGL resources held by this object. Destroying an object allows for deterministic release of WebGL resources, instead of relying on the garbage collector to destroy this object.

Once an object is destroyed, it should not be used; calling any function other than isDestroyed will result in a DeveloperError exception. Therefore, assign the return value (undefined) to the object as done in the example.

Throws:

DeveloperError : This shader program was destroyed, i.e., destroy() was called.

Returns:

Example

shaderProgram = shaderProgram && shaderProgram.destroy();

See:

• ShaderProgram#isDestroyed
• glDeleteShader
• glDeleteProgram

isDestroyed

Returns true if this object was destroyed; otherwise, false.

If this object was destroyed, it should not be used; calling any function other than isDestroyed will result in a DeveloperError exception.

Returns:

Boolean True if this object was destroyed; otherwise, false.
