# CudaFractal
Generates fractal images using Nvidia's CUDA framework.
## Usage
### Install
[REWRITE INSTALL]
### Command Line
The format is `> CudaFractal [options]` The options are as follows
| Option | Description | Default |
|:--------------:|:-------------------------------------------------------------------------------------------------------:|:-----------:|
| --help | Print help message (overrides all other options) | |
| --cmaps | Print list of available colormap presets (overrides all other options except help) | |
| --xml arg | Generate fractal images from an xml file (see below. overrides all other options except help and cmaps) | |
| --mbrot | Generate mandelbrot image (overrides cr and ci options) | |
| --cr arg | Set real component of complex constant to arg | -0.4 |
| --ci arg | Set omaginary component of complex constant to arg | 0.6 |
| --width arg | Set width of image to arg | 1920 |
| --height arg | Set height of image to arg | 1080 |
| --zoom arg | Zoom image by arg | 1.0 |
| --rotate arg | Rotate image by arg degrees | 0.0 |
| --transx arg | Translate image horizontally by arg | 0.0 |
| --transy arg | Translate image vertically by arg | 0.0 |
| --cmap arg | Set colormap preset being used to arg | nvidia |
| --file arg | Set filename being saved to to arg | fractal.png |
| --mnemonic arg | Set mnemonic to arg (best used by scripts to identify what fractal is being made) | fractal |
| --verbose | Print verbose messages in program | |
### XML File
Fractals can be specified in an xml file, and can be read in the program using `> CudaFractal --xml [xml file name]`
The XML file format is as follows:
```
[fractal specs...]
```
A list of fractal specs within the "fractals" tag.
Each spec has the following format:
```
[colormap spec...]
```
#### Colormaps
Colormaps can be specified in three ways. The default colormap is greyscale black to white.
##### Presets
Colormaps can be defined by preset as follows:
```
```
##### Gradient
Gradient colormaps can be defined as follows:
```
```
(see Colors section below)
##### Sinusoid
Sinusoid colormaps can be defined as follows
```
```
`alpha` defaults to `255`. `r`, `g`, `b`, values default to `0.0`
##### Colors
Colors can be defined by either using a `hex` (or `hexa` with alpha channel) value
```
```
`hex` and `hexa` values default to `0x0000000`
Or by the individual `rgb` (or `rgba` with alpha channel) values
```
```
`r`, `g`, `b`, and `a` values default to `0`
