OpenGL displacement shader for iOS app

We are looking for a passionate developer to craft a visual effect within an iPhone app.

Project description

- The app should display a rendered image that is the result of a 2-passes process: first, with a pixel displacement, and second, with a compositing over a background (cf attached reference picture):

- Pass 1: the process should displace the pixels of a 32bit transparent texture image according to a 48 bit displacement map image (using Green channel for X position and Blue channel for Z position).

- Pass 2: the process should composite that 32 bit displaced image over a 24 bit background image based on the alpha channel.

- Whenever the displacement image has an RGB color of (0,0,0), the resulting image should be transparent (RGBA value of (0,0,0,0)).

Requirements

- The final delivery should include a functional iPhone app with an Xcode project, the application's source code and the effect/shader's code.

- The displacement shader should handle 48 bit image sources to provide high resolution displacement coordinates (16 bit per channel).

- The shader should include anti-aliasing/subsampling treatments to render smooth displaced images.

- The shader effect should be optimized for speed.

- The shader can be programmed using Core Image, OpenGL ES or even rely on third-party frameworks such as GPUImage.

Initial resources

- A transparent texture image (32 bit PNG)

- A displacement map image (48 bit TIF)

- A background image (24 bit PNG)

- A sample process sheet (24 bit JPG)
