Problem 3D imaging: making 3000 coordinates into a solid 3d image
I've got coordinates(3000 times x, y and z) of a bonepiece.
I want to make it a solid bonepiece and I thought of connecting the coordinates(three at the time) wich are close together with trisurf or tetramesh. somehow, matlab doesnt find the coordinates which are closest to eachother. I tried to solve it with griddata but that doesnt work because it has a problem with seeing wich points are the top of the bone and which are the bottompoints of the bone because it searches for coordinates in x and y and it forgets z.

The aim of my project is to fire a beam of laser onto a target which is supposedly a black circular cardboard(10 cm diameter) placed on a white wall of 2m x 2m at a distance of 1m from the laser. The target can be placed at any random position on the wall and laser must automatically orient itself so as to be inline with it. Both the target and the wall are assumed to be stationary.
Is there any program to obtain the 3d coordinates(with respect to a reference point) of the blackspot from it's corresponding 2d image? I want the spatial orientation of the black spot with reference to the la...Put a 2d plot and an image into a 3D coordinate system
I am trying to make a series of images with IDL for my simulations. After exploring the new IDL graphics system and the coyote graphics for over 3 hours, I still don't get a good concept of how to do it.
So, here is a sketch of what I am after:
In the sketch, the simulation is basically a color-scale image of current density in the 2D simulation plane, which moves along the z-axis as the simulation goes.
Can anyone help me with this, please? I really appreciate it.
BTW, as a starting point for making this kind of plot, I used the...Mapping Resized image coordinate to Original image(before resizing) coordinate
if I select a coordinate in a resized image is there anyway to find
out the corresponding coordinate in the original image?
...how to merge bifurcation points in 3D images and i wanna get 3D thermal images.
I am a beginner in matlab and I wanna to know how to merge bifurcation points in 3D thermal images. I wanna get sample 3D thermal images.

Well, I suppose you could use image processing and MATLAB. Other than
that I have no idea, especially since you didn't post any pictures

I have 3D image (generic model) after reading it I will get n*3 matrix. But in order to use interp3 if I pass this 3D image to this function it is giving error. Like V must be 3D array.What shall i do. Please give the suggestion.

What does the n*3 matrix represent? Unconnected points that are known to

Hi, I'm new to this newsgroup so apologies if I inadvertently breach
My problem is that I require coordinates in OpenGL space from coordinates
given by the position of the mouse cursor.
The program I am writing consists of causing explosions at coordinates in
OpenGL space and I am looking to create explosions when clicking with the
mouse pointer. Hence why I would like OpenGL coordinates from the position
of the mouse cursor.
I have used the selection buffer for object selection in the past, but this
does not provide sufficient accuracy for my purposes.
Any suggest...3D coordinate to 2D coordinate
I have a function with 3 variables, x1, x2, x3, and the
value of the function is negative or postive. I want to
show this log(x2/x1) and log(x3/x1) coordinates.
Should I just set x1 = 1.0, and evaluate functions with
x1 = 1.0; x2 = exp(log(x2/x1)); and x3 = exp(log(x3/x1)); ?
Is this how I should go?
Thank you for a help in advance.
So, function values of various combinations of x1, x2, and x3 will be 0
or 1, and
it will create matrix of 0's and 1's. I want to express this in x-axis
as log(x2/x1) and
y-axis as log(x3/x1) instead of x1 for x-axis, x2 for y-axis, and x3
for z-axis....Convert 2D image to 3D image
