FXO file extension - Microsoft DirectX pre-compiled pixel/vertex shader
What is fxo file? How to open fxo files?
File type specification:
The fxo file extension is associated with the DirectX, a pack of applications programming interfaces for Microsoft Windows, used by developers for programming video games and multimedia applications for Microsoft platforms.
The fxo file stores pre-compiled pixel, or vertex shader data.
The vertex shader is used to transform the attributes of vertices (points of a triangle) such as color, texture, position and direction from the original color space to the display space. It allows the original objects to be distorted or reshaped in any manner.
The pixel shader is another programmable function that allows flexibility in shading an individual pixel. Whereas vertex shaders can be used to completely transform the shape of an object, pixel shaders are used to change the appearance of the pixels.
The pre-compiled pixel/vertex shader format is used by various computer games programmed for Microsoft Windows and distributed via Steam service and others.
