It seems that I must practice more to improve my expression^^
Richard Kennaway’s explaination(“a school of fish” & “insect”) is exactly what i meaned. I put a video clip of my simulated “cricket”(six-legged insect) on CSGnet last year.
However, I shouldn’t use “convex” here. The word “convex” is used in that 3D rendering engine(OGRE 3D) to represent a special type of shape for short. This shape can be created by its vertices(vertexes). If you have seen the screenshot attached, the white object among those green balls is a kind of convex shape.
It’s my pleasure to talk about my experience on PCT and reorganization. The programme is a Windows application and requires a certain driver’s support(a physics simulation engine called PhysX). Most PCs are able to run it.
Best, (It’s the same meaning with yours^^)

This is a quote from a paper named “ROBUST VARIANCE REDUCTION FOR
RANDOM WALK METHODS”: Random walk methods are effective for solving
linear partial differential equations in many dimensions, especially
those involving complex geometries.It’s just what e coli is doing.
Thanks, Bo, that is useful information. I’ll be very interested to
hear more. Will your program run on a PC? If so, I hope you will
demonstrate it and give a talk about it at the CSG meeting in July. I
will bring my laptop and there will be a projection device to use
with a large screen. I think there will also be high-speed internet
connections available.Your English is more than good, it is excellent – but once in a
while you seem to be using a word with a meaning I can’t guess. I
can’t
really complain, since my Chinese is a total failure, but
perhaps you will enlighten me about what you mean by “cricket” and
“convex” in the following:I built a new programme these days with my “Physics lab”(The
platform I showed my cricket). Some green balls evolve to chase a white convex."Cricket"is the name of a British ball game. It may also be a
communication device (???). And “convex” is an adjective referring to
a shape like the outside surface of a ball (“concave,” the opposite
of convex, would indicate the shape of the inside surface of a bowl).Also, “shoal”:
The whole looks like a shoal chasing crumbs.
The word “shoal” means a place in a lake or ocean where the bottom
rises close to the surface. It is related to “shallow.” I wonder if
you might mean a “school” (of fish), pronounced "skool’. In this
expression, “school” is used poetically to mean a “group” like a
group of school
children running around together.PCT is truly becominbg an international science.

P.S. If I’m telling you things you already know, just smile and say “I know.”
