[PATCH 00/12] Tessellation support for nvc0
This is enough to enable tessellation support on nvc0. It seems to
work a lot better on my GF108 than GK208. I suspect that there's some
sort of scheduling shenanigans that need to be adjusted for
kepler+. Or perhaps some shader header things.
Even with the GF108, I still get occasional blue triangles in Heaven,
but I get a *ton* of them on the GK208 -- seemingly the same issue,
but it's

N-dimensional delaunay tesselation & voronoi diagrams
Hi,
I've been looking for functions that can do delaunay tesselation and
generate voronoi cells. I came across deldir and tripack but both seem
to be restricted to 2D points. Are there any packages that can do a
tesselation in N dimensions? I know that Matlab and Mathematica use the
qhull package to provide functions for this. Does anybody know of any R
packages that do this (maybe by calling

Advanced testing tutorials on Web?
Everyone talks testing, but I don''t see much about it.
I have been searching the web for about 5 hours and I can''t seem to
find a good, advanced tutorial on the latest trends in testing.
Everything is either outdated or very simplistic.
Does anyone know where I might find good testing
What are you using?

[spatstat] Convert shapefile to pixel image
Dear all,
I am currently working with the spatstat package, using windows and pixel images.
First:
My aim is to transform a shapefile (see attached) into a pixel image.
My idea is to start transforming the shapefile into a Spatial Polygon file:
x <- readShapeSpatial("200001441.shp")
y <- as(x, "SpatialPolygons")
z <- as.owin(y)
Given z, I want to identify each

lasso for variable selection
For "importance" it's probably best to stick with absolute values of
coefficients, instead of value of the penalty parameter for which the
coefficients changed to non-zero.
Friedman skipped a lot of details on his rule ensemble in that talk, due to
time constraint. In his implementation he was using his own algorithm,
PathSeeker, for which paper and software are available on his

Festival tts
Hi I have installed Festival on the same box as asterisk and followed the
instructions to integrate it with asterisk.
Festival seems to work fine on its own performing text to speech from the
command line or via a file.
Asterisk answers the call but there is no speech. I can see no errors in the

SPATIAL QUESTION: HOW TO MAKE POLYGONS AROUND CLUSTERS OF POINTS AND EXTRACT AREAS AND COORDINATES OF THESE POLYGONS?
Imagine that I have a large number of points (given by coordinates x and y) that vary in density per space. For the purpose of demonstration it could be generated like this: s <- data.frame(x=runif(10000,0,900),y=runif(10000,0,900)); plot(s)
I want to create polygons around the points where point density is greater than a selected threshold (for example, by using krieging or equivalent

voronoi/Delaunay/Dirichlet tessellation on sphere in R or S?
There's Renka's STRIPACK, and TRIPACK, respectively, ACM TOMS Algorithms
772 and 751, and there's the R package "deldir" which does the Delaunay
for a plane, but does anyone have or know of the tessellation in R for a
sphere?
Also, is there a standard indexing scheme for Delaunay facets, and
perhaps of edges in such facets? I'd expect that to be a publication

tessellation from biological data in spatstat
Hi,
I'm new to this mailing list so apologies if this is too basic. I have
confocal images 512x512 from which I have extracted x,y positions of the
coordiates of labelled cells exported from ImageJ as a.csv file. I also
have images that define an underlying pattern in the tissue defined as
areas of different pixel values 0 or 255 (also 512x512) I've exported
these images as .txt

Spatstat Tessellation error
Hello R Users,
I am trying to do a quadrat count defined by covariate properties in
spatstat. I have read my elevation raster into R (from ascii) and converted
to class "im" for use in spatstat.
Now I have point data of class "ppp" which window is the same extent as the
elevation image. I can conveniently plot the image and the points on the
image as follows:

voronoi tessellations
Okay, been working with tripack, seems the most mature package for this. Got it to work well with their test data set - data(tritest). When i tried random numbers to explore further, i am getting some results that don't reconcile.
example run this:
library(tripack)
y <- runif(100)
x <- runif(100)
vm <- voronoi.mosaic(x,y)
plot(vm)

Tessellation shaders get MEM_OUT_OF_BOUNDS errors / missing triangles
Hello,
I've been debugging a few different tessellation shader issues with
nouveau, but let's start small. I see this issue on my GK208 with high
frequency, and I *think* I've seen it once or twice on my GF108, but
it's exceedingly rare, if it does happen. I don't have a GK10x to test
on, unfortunately, but I assume it'll have the same issue as the
GK208.
The issue is

Tessellation shaders get MEM_OUT_OF_BOUNDS errors / missing triangles
One additional observation that I just made is that on GK208, the blob
apparently doesn't use the result of S2R Rx, SR_INVOCATION_ID
wholesale in TCS. It either passes it through a I2I.S32.S32 Rx, |Rx|
(i.e. absolute value), or even more paradoxically, shl 2; shr 2; which
removes the top *2* bits, rather than just the top 1. However I see no
such behaviour on GF108.
I'm going to test out
