Hi, I am getting a NullPointerException when calling to renderScene (buffer)

I am sure than neither the world nor the FrameBufer is null, so the problem must be a bug os something becausse it happens sometimes. not always.

I have tested the app on 2 machines. and this happens mostly on my P3 laptop with a GForce 2. on my P4 qith a fx 5600 almost never happens this.

this is the stackTrace:

Java version is: 1.6.0
-> support for BufferedImage
Version helper for 1.2+ initialized!

Basicly this happens when I want to switch Worlds for rendering.

Hi, how can I blit an image in a diferent size than the original pic.

I have a pic of 800x600 and I want it to be blitted on all the screen but the resolution is not always of 800x600 so I need it to be resized on somehow.

Is there anyway to change the size of the original pic?

Is there anyway of changing the size of the texture used for blitting?

Can I get the distance from a point to an Object3D?, not just getting the difference from its centers, but calculating a perpendicular projection from a point to the body?. I will post images later

Hi, how can I do this. for example a cube on a horizontal that begans to climb for an inclinated plane. The Object3D class has only check for collision methods but they do not slide nor adjust the rotaion of the object, how can I do this?

ok I have this suggestion:

I would want that jpct could draw and renderScene of certain objects3D or maybe from an ArrayList of object3D. Now why?

To be able to show just some objects and later add another ones. The use I am thinking is a lightweight sky or enviroment.

for example we can use a small sphere placed always arround the camera and this sphere can have an sky texture. Now we could draw and render only this Object3D and the overwrite the parts drawed by the rest of the world. this would result on drawing the sky only and the drawing the rest, like if there were 2 main layers on the final render to be displayed!

Hey, I guess I am back to jpct for my Thesis. This time I MUST finish it to be able to get my degree so I hope to finish the project this time. Not as in Flier Match.

Hi, I am having a problem at receiving some data via a network.

I use the DataInputStream to read the data from a Socket. I always used to ask first for the number of bytes to receive, then create a byte array and store the data on there. The problem is that I need to read the data without asking the number of bytes. I tried reading until getting the -1 from the read method that means the end of the transmition, but the -1 is never read until  the client closes the stream. That would be easy to solve just asking the client to close the stream, but the problem is that the client WONT close any stream because is not programmed on java but on another language that doesnt allow to close the streams.

What I am doing now is this:

1.- creating a byte array of 197 slots.

2.- read on it until the number of bytes read is different from the array length.

3.- store the parts on a file, if the number of bytes is different from the array length then add the new part to the file and finish.

this works but I am afraid that is the number of bytes to read is multiple of the array length then the server will blocked until getting new data. and thats a problem because I need to answer inmediatly with another things.

Hi, I hope anyone can help me, I need to began an internet connection from my java app. What I need this because my app asumes that not everyone has a 24/7 connection, so based on a Schedule on certain times I need to send some data and close the connection when finished. How can I do that.

The dial up connection is already done and has on it the username and the password.
