EVOLVOTRON_RENDER(1) Evolvotron EVOLVOTRON_RENDER(1)NAME
evolvotron_render - Render an evolvotron function tree to an image.
SYNOPSIS
evolvotron_render [-f <frames> ] [-j] [-m <multisample> ] [-s <width> <height> ] [-spheremap] [-v] <imagefile.[png|ppm]> < <file.xml>
DESCRIPTION
evolvotron_render reads an evolvotron image function from it's standard input and renders it to the file specified (suffix determines type,
defaults to ppm if not recognised).
Image functions can be obtained by saving them from the evolvotron applicaiton, or using evolvotron_mutate.
See the evolvotron manual (accessible from the evolvotron application's Help menu) for more information on image functions.
COMMAND-LINE OPTIONS-j Enable sample jittering.
-m <multisample> Enables antialiased rendering. This specifies the size of the sub-pixel sampling grid, so 1 provides the default one-
sample-per-pixel behaviour, while 4 provides 16 samples per pixel on a 4x4 grid. Unlike the main evolvotron application, there is no
upper limit, but of course rendering time increases as the square of this number.
-s <width> <height> Specify resolution of output image. Defaults to 512 512.
-v Verbose mode; useful for monitoring progress of large renders.
-f <frames> Generates multi-frame animations. .fnnnnnn is inserted into the specified filename (before the filetype suffix, if any).
You can use this on functions which weren't evolved in animation mode, but there's no guarantee they have any interesting time/z vari-
ation.
-spheremap
Create a spheremap instead of a planar texture.
EXAMPLES
evolvotron_mutate -g > function.xml
evolvotron_render -v -s 2048 2048 function.ppm < function.xml

GLTEXIMAGE2DMULTISAM(3G) OpenGL 3.3 GLTEXIMAGE2DMULTISAM(3G)NAME
glTexImage2DMultisample - establish the data storage, format, dimensions, and number of samples of a multisample texture's image
C SPECIFICATION
void glTexImage2DMultisample(GLenum target, GLsizei samples, GLint internalformat, GLsizei width, GLsizei height,
GLboolean fixedsamplelocations);
PARAMETERS
target
Specifies the target of the operation. target must be GL_TEXTURE_2D_MULTISAMPLE or GL_PROXY_TEXTURE_2D_MULTISAMPLE.
samples
The number of samples in the multisample texture's image.
internalformat
The internal format to be used to store the multisample texture's image. internalformat must specify a color-renderable,
depth-renderable, or stencil-renderable format.
width
The width of the multisample texture's image, in texels.
height
The height of the multisample texture's image, in texels.
fixedsamplelocations
Specifies whether the image will use identical sample locations and the same number of samples for all texels in the image, and the
sample locations will not depend on the internal format or size of the image.
DESCRIPTION
glTexImage2DMultisample establishes the data storage, format, dimensions and number of samples of a multisample texture's image.
target must be GL_TEXTURE_2D_MULTISAMPLE or GL_PROXY_TEXTURE_2D_MULTISAMPLE. width and height are the dimensions in texels of the texture,
and must be in the range zero to GL_MAX_TEXTURE_SIZE - 1. samples specifies the number of samples in the image and must be in the range
zero to GL_MAX_SAMPLES - 1.
internalformat must be a color-renderable, depth-renderable, or stencil-renderable format.
If fixedsamplelocations is GL_TRUE, the image will use identical sample locations and the same number of samples for all texels in the
image, and the sample locations will not depend on the internal format or size of the image.
When a multisample texture is accessed in a shader, the access takes one vector of integers describing which texel to fetch and an integer
corresponding to the sample numbers describing which sample within the texel to fetch. No standard sampling instructions are allowed on the
multisample texture targets.
NOTES
glTexImage2DMultisample is available only if the GL version is 3.2 or greater.
ERRORS
GL_INVALID_OPERATION is generated if internalformat is a depth- or stencil-renderable format and samples is greater than the value of
GL_MAX_DEPTH_TEXTURE_SAMPLES.
GL_INVALID_OPERATION is generated if internalformat is a color-renderable format and samples is greater than the value of
GL_MAX_COLOR_TEXTURE_SAMPLES.
GL_INVALID_OPERATION is generated if internalformat is a signed or unsigned integer format and samples is greater than the value of
GL_MAX_INTEGER_SAMPLES.
GL_INVALID_VALUE is generated if either width or height negative or is greater than GL_MAX_TEXTURE_SIZE.
GL_INVALID_VALUE is generated if samples is greater than GL_MAX_SAMPLES.
