Fragula lets you view your fragment shader changes in real time. Simply save your fragment shader while editing and watch your changes appear in the Fragula window in real-time.

Installation

To install Fragula run cargo install fragula in a terminal prompt.

Usage

``` USAGE: fragula [OPTIONS]

FLAGS: -h, --help Prints help information -V, --version Prints version information

OPTIONS: -t, --texture The file path to the texture image to load

ARGS: The file path to the Obj file to load The file path to the fragment shader to load

```

To use Fragula you can run fragula in a terminal with the path to the OBJ file and fragment shader you would like to use:

$  fragula my_3d_model.obj fragment.glsl

If you have an image texture that you would like to use in your fragment shader you can use the --texture or -t flag:

$  fragula my_3d_model.obj fragment.glsl -t my_image_texture.png

You can scale, translate, and rotate your model using the following keys:

R: Reset the model back to its original state W: Rotate the model counter clockwise about the x axis S: Rotate the model clockwise about the x axis D: Rotate the model counter clockwise about the y axis A: Rotate the model clockwise about the y axis Q: Rotate the model counter clockwise about the z axis E: Rotate the model clockwise about the z axis C: Translate the model in the negative x direction V: Translate the model in the positive x direction B: Translate the model in the negative y direction N: Transalte the model in the positive y direction Z: Scale the model in negative increments X: Scale the model in positive increments
