I'm trying to use a matrix to make my terrain.


I get these lines between my tiles. I know that there is a certain amount of "bleedover" that occurs, but how do I get rid of it? Any suggestions?

All images loaded are prepared with mipmaps if they do not already have them.
load image "C:\Textures\tiles.dds",1,1
This will load the image without adding mipmaps

Hope it helps.

Sorry. I was wanting to preserve it as much as possible. Sorry for the post, I figured it out about 20 seconds after I posted. I needed to use:

It's not perfect, but there are no lines now.

I must say, I was intrigued by your solution. I tried it on a project I am working on. It looks a little better but I still get lines. I don’t understand theoretically it should work.

Adding a value of one will preserve the image without adding mipmaps.

Well, I think the diminsions "should" be 1/imagewidth,1/imageheight....? That's what worked for me. Though it still isn't perfect, the lines are gone.

My texture image is 512x512. The first trim values I tried was,

SET MATRIX TRIM 1,1.0/512.0,1.0/512.0

Then I tried it with the tile size 256x256. I have tried every trim value up and down the spectrum. I have set the matrix transparency flag. It did produce some cool effects but I still get lines.

Make a simple example code. Try it out. If you still have the same problem, post a screenshot and the code so we can look at it. It may be worth your time to upload your tile image.

I have simplified my project into a simple example. Attached is the source code and files. It seems when I added it to my project it looked better because matrix transparency was set. The example has that line commented. It looks even worse. Also in the example are included a snapshot with and without transparency. This doesn’t make sense.

Thank you.

Notice the first line to set the display mode. The 5th parameter is for multisampling-- I used a value of 3.
Also, when you load the image, you have to have the 3rd parameter as a 1 to preserve the quality.... Not sure why DBP doesn't do that anyway..?

That change made it work for me. Try it out.

Thanks again.
