Why does OpenGL not support multiple index buffering?
(1 answer)
Closed 12 months ago.
I can't seem to have a grasp on OpenGL VAOs and VBOs.
I am coding an OBJ Loader from scratch (BTW I am using LWJGL) and I can't seem to get the order of normals correctly. When I look at the OBJ File I notice that there are positions with different normals and the face contains index numbers for position, texture, and normals. I don't know how to order them properly so that my normals would be assigned into correct positions when the engine starts rendering.

JFreeChart solution to draw a graph with a lot of data (>100) or (>1000)
(1 answer)
Closed 5 years ago.
I make a JFreeChart from ChartFactory and I put a lot of values to it by calling method: categoryDataset.addValue(...) and then I put categoryDataset to JFreeChart object and that's how I make chart. Due of vast amount of values, my X axis is blurred:
As you can see there are no key values on axis cause there are too many of them. I would like to print on it like only a few values (every 10% interval) so it's readable.
Any advice would be appreciated :)

How to draw custom rounded rectangles in java?
(1 answer)
Closed 6 years ago.
I need to draw a rectangle with the top-left and bottom-left corners, and another rectangle with the top-right and bottom-right corners, rounded.
I know you can draw a rounded rectangle using Graphics2D#drawRoundRect, but that rounds all four corners.
I think this question haves an answer here https://stackoverflow.com/a/20321954/4443053
Basically, you need to define your own shape. I-m pretty sure you can modify that example to your needed corners.

I am trying to match a prerecorded 3d(float x, float y, float z) linked list to another 3d linked list(float x, float y, float z). There is about 50 prerecorded sequences with 1000 examples of the same move every time, against which I am trying to match through.
The size of linked lists highly vary.
Is there a specific neural network pattern/library/framework/algorhytm in Java I could use for this task ?
Any suggestions would be highly appreciated!
Waiting for your replies)
If you insist on a neural network...
Simplify your prerecorded input
For each 3d point list create 3 black and white 2d images of your points (drawing a line between each adjacent point)
Top-down (x,z)
Forward-back (x,y)
Left-right (z,y)
Simplify your user input
Create the same 3 black and white images (explained above)
Find the bounding box of the points and scale the image to a uniform size
Having your user input, scaled to same size as your prerecorded input will facilitate recognition
Create neural networks for image recognition
Create a trained network for your prerecorded (3 images for each)
This seems like it would work http://neuroph.sourceforge.net/image_recognition.html
Build your neural nets from the black and white images (that represent the 2d mapping of your 3d points onto the 3 perpendicular planes)
Experiment with your matching bounds/constraints
IF Top2Bottom >= 0.75 AND Forward2Back >= 0.75 AND Left2Right >= 0.75
THEN IsAMatch = True
ELSE IsAMatch = False
I would probably just generate a large 3d corridor (think wide 3d tube, or a collection of connected cylinders) that represented the extremes of my prerecorded points then scale the user input points then check if the user input points fall within the matching corridor.
EDIT Very odd that the question itself was down-voted and closed, then days later my answer was down-voted. Realistically, the question was likely closed due to a failure of group think on the part of the moderators. Maybe it then looked a little awkward to have a closed question with a +1 "Accepted" answer, so this answer was subsequently down-voted (twice).
From my experience, the only way to ask a question like this is to either slap a large bounty on it, or re-word it in a way that won't offend the fragile sensibilities of the moderators (most of the time they do a good job and don't overstep...).
