app

animator

An application that interpolates 3D pose mesh files and displays an interactive animation.

The building system only supports Linux systems at the moment, although it should be straightforward to port it to other platforms.

Requirementes

• surfmorph (included in the repository)
• Eigen
• OpenMesh
• Qt 5
• libQGLViewer

Compilation

Clone this repository and navigate to this directory. Then run:

$ mkdir -p build
$ cd build
$ qmake ..
$ make

Usage

After compiling, an executable animator should have been created in the build directory. The program must be called from a command line with the following syntax:

$ ./animator [options] <pose files...>

Where pose files... must be two or more mesh files containing the different poses of the model. The mesh files must have the same number of vertices and triangle structure, and the vertex indices must be registered correspondingly. The posible values for options are:

• -f|--fps <fps> to specify the frame rate of the animation.
• -d|--duration <seconds> to specify the duration of the animation.
• -h|--help to show a help message.
• -v|--version to show the application version.

After computing the animation frames, the animation will play repeatedly in an interactive window. Press H key to see an integrated help window. The controls of the animation window are basically the default controls defined by libQGLViewer, with the following additions:

• Press + to accelerate the animation.
• Press - to decelerate the animation.
• Press B to enable or disable the backwards animation in the loop.
