Auto-generated palm trees. . .

More work done on my island project. . . not sure what this will turn into but it looks pretty.

No.

The textures and shape are wrong.

This is a palm tree:

Notice how yours have the wrong bark, and your branches (leaves? I'm not sure what part of it qualifies as the leaves) are pointy and shooting out in all directions, wheres they should grow out primarily upwards (about a 135 degree range from normal of the last segment of the trunk if I were to guess) and curve down.

The meshes are originally designed for deciduous trees which explains the wrong bark and the wrong leaf mesh shape. All I did was change the leaf texture and reduce the spread+number of branches, so I was just experimenting.

I will take on your ideas for the final models though - thanks!

Here's what the original trees were like:

Those do look good -- not SpeedTree good, but considering the usual standard of graphics in Blitz3D, they're good.

Okay . . . is this an improvement?

and here's a tree with lots of detail...

Much better, not perfect, but it'll work for anything practical.

thanks!

Yeh, the new version of the palm tree is better.

I wish Blitz3D could use SpeedTree - sniff. Still BlitzTree3D is an excellent alternative.

Those palm trees are better, but your bark is very much not right. Palm trees have one big thick trunk with various `ribbed` sections, and it definitely doesn't look smooth. The trunk you have at the moment looks more like a silverbirch.

I suggest to use a bigger texture for the leafs, so you can use fine structures like the real ones. you may even take s photo of real palm leafs, then use my mask utility to paint the background with a mask color: http://www.blitzbasic.com/codearcs/codearcs.php?code=795

Search EG. the google images library for palm trees to get some high resolution palm tree leafs:

Just made some better leaves using a quick algorthim I wrote.
I then took the output of this and used photoshop to add texture to the plain color areas.

Here's the code - someone might be able to modify it for something else:

Graphics 800, 600

SetBuffer FrontBuffer()

Const centerX# = 256
Const centerY# = 256
Const brLen# = 355
Const Spacing# = 10

For ang# = 45.0 To 315 Step 90.0
	Color 255, 155, 100
	
	For i = 1 To 100
		Line centerX+Rnd(-3,+3), centerY+Rnd(-3,+3), centerX + brLen * Cos(ang), centerY + brLen * Sin(ang)
	Next
	
	
	
	Color 0, 155, 0
	For n# = 1 To brLen Step Spacing
		For n2# = n To (n + Spacing*0.5) Step 0.7
			cx# = centerX + n2 * Cos(ang)
			cy# = centerY + n2 * Sin(ang)
			
			
			lLen# = 100*Cos(n/2.5-50)
			lLen = lLen * Rnd(0.2, 1.2)
			
			ang2# = ang-35
			cx2# = cx + 0.02 * (brLen-n) * Cos(ang2)
			cy2# = cy + 0.02 * (brLen-n) * Sin(ang2)
			Line cx2, cy2, cx2 + lLen * Cos(ang2), cy + lLen* Sin(ang2)
			
			ang2# = ang+35
			cx2# = cx + 0.02 * (brLen-n) * Cos(ang2)
			cy2# = cy + 0.02 * (brLen-n) * Sin(ang2)
			Line cx2, cy2, cx + lLen * Cos(ang2), cy + lLen* Sin(ang2)			
		Next
	Next	
	
Next

An update on my trees. . .

My latest palms:

My latest beeches:

At the moment the detail is way too high for more than 5 or 6 trees at a time, and I still have to write a better mesh generation function to avoid the gaps between branch segments, but I'm working on LOD and a few other things and maybe I feel a new tree system coming along. . . :O)
