[Solved] Display part of text

[Patrik]

Hello

 

I was wondering if it's possible using the built in text function to somehow only render part of the text on the y-axis. (see picture)

 

 

 

How would you achieve this result?

Scale it? Render all text and erase the parts no wanted?

Make a small buffer and render it to it.

Ok, thanks for the tip.

 

 

I also found another way to do it also using the glScissor(x, y, width, height) command.

glScissor command

 

Then you can specify an area on the screen and stuff rendered outside that area will not be shown.

Do you have an example for using glScissor? I just can't get it working together with the coordinate system ...

 

Thanks!

I don't have access to my computer with the code at the moment.

 

The problem may be that glScissors uses the bottom of the screen as it's 0 coordinate on the Y-axis and the drawing commands uses the top of the screen as 0 on Y-axis.

 

You can check if this is the case by by setting the glScissor to something like glScissor(10, 50, 20, 20 ) and then draw one rectangle that covers the whole screen. Then it should only render a 20x20 sized cube on the left side either at the top or bottom.

 

If it gets rendered at the bottom this is the case. Then you need to offset the glScissor(x, y, width, height) command's y parameter with the height of the screen resolution to get the wanted position.
