Squared Images - Is It Still A Good Idea

[Guest Red Ocktober]

is using a non squared image asking for trouble in todays world of exotic graphics cards?

 

i've got a 982x679 image being used as a texture... should i square it off...

 

thx

It's power-of-two you should worry about, not square. 512x1024 is perfectly fine, for example.

 

A non-power-of-two texture will probably work fine on everything out there. However, it won't have mipmaps. I would only use these for 2D graphics being drawn on the screen, and would certainly not use it for a 3D texture.

Yes. Power of 2 is very important.

I would also be careful with non-square images. Had a weird experience on some devices (mostly mobile) where the non-square images showed up completely white. This happened only on moving images though, such as sprites, etc...

That article is not relevant to Leadwerks. This engine does not attempt to resize textures.

Is that because Leadwerks doesn't support old cards which would require this? (I may not understand the concept correctly.)

[Josh]

I don't know what old cards don't support non-power-of-two textures. There might be some, but I don't know.

[gamecreator]

Ah, ok. For some reason I thought old video cards required this, like how they couldn't handle textures larger than 1024x1024. Just a misunderstanding on my part. Since it's just an engine limitation, it's awesome that we don't have to worry about it with Leadwerks.

Regardless it is good practice

Regardless it is good practice

With respect, not if you're using Leadwerks. And it has several other benefits, such as smaller file sizes for textures/bump maps/specular maps/etc. and not needing to be obsessive about fitting textures in predetermined sizes when designing models.
