Hehe, matrices can be a pain, they seem to defy logic sometimes.

Now get to sleep before you have an episode.

Completely wrong... o_O That is 1 matrix... not 2... Its a height map covered in a texture... simple as that... ^_^ If you have any more questions ask... =\

Yea, how do you make heightmaps?

I know what a heightmap is, but how did you go about making it?

personally i just make a cheesy height map using dif colors for each elevation, if its of this then use (color) or if its under theni use some color, but they look like sh*t.

A heightmap is a painted map that represents a heightfield.The darker colors on the painted map being lower, and the lighter ones being higher.So it's basically a black and white picture, that will make a heightfield.I think I now know where to begin when making a heightmap, but I'd appreciate any help Puffy.

Yellow:

The heightmap (or bumpmap) is a gradually shaded 'greyscale' image which can be produced with software, or a paint program like Paintshop Pro. The smoother the gradient between high (bright) and low (dark) areas of the image, the smoother the resulting hills on your matrix.

You have to read the raw data from the greyscale bitmap file and get an average of the red, green and blue pixel data. From this you can calculate a height value to apply to the matrix.

It's a little more complicated than that as you have to make the heightmap image data fit the matrix - regardless of the size of both.

As you said, the brighter the shade of grey, the higher the resulting point on the matrix, but another fun aspect is that there's no real way to figure out how high any given shade of grey equates to.

That's why I added a 'greyscale compensation' slider bar to MatEdit Pro, so when you have applied a bumpmap to your matrix, you can use the slider to alter the greyscale threshold - effectively allowing you to increase and decrease the brightness of the bumpmap while watching the matrix raise and lower while you do it.

Best way to make a height map is to use Terragen.

You are completely right Exeat... ^_^ but for more controled textures I use texturemaker... =\ with the noise thingy... set to heightmap moutain... noise thingy = perlin noise... under generator =\ the moutain command without the lil square icon thingys... although its a good way to make your flat points look better... =\ Hrmmm in mine I have a value that represents the heighest point... so pure white would be that point... and everything inbetween is just in respect to the highest point... =\ ok... here lemme give you guys steps... oh yes... and I loved MatEdit back with the original darkbasic TDK...

1) You will need a max matrix height... something to scale the height off of...

2) Something to hold the values for the total Width and Height of the bitmap (100/100... 256/256) etc....

3) Something to tell the heightmap how many pixels of your heightmap represent 1 square... so 100/100 matrix would be a ratio of 1... a ration of 2 would say that you want a 50/50 heightmap... or whatever... if its a 100/50 bitmap... it would be 50/25 matrix... you can also scale this up... so every 1 pixel = 4 squares... etc... except that makes kinda blocky unsmooth stuff if you don't do it correctly...

4) You are going to need a blur factor... this is a classic... if you have a jagged heightmap then this will make it smooth... ...

5) A scale... so if the scale is 30 then your matrix will be 3000 by 3000 in this case... (100/100 square bitmap)...

6) SET THE CURRENT BITMAP TO THE HEIGHTMAP AND LOCK THE PIXELS... VERY IMPORTANT...

7) Make a funtion that scans each pixel of the bitmap... =P gets its values... ... your going to need an array... of course... (remember the point(x,y) command.... =P...

8) Apply your blur factor... =\...

9) Apply the scale factor... and the max height... ^_^

10) Make the matrix... do the whole scale thingy... remember about the tile scale too...

11) Apply the heights to the tiles retrieving info from your array... and then setting the height...

12) Texture... an easy way... (like I use) would be to use Texture Maker... with the multilayer command... it makes excellent textures... Then you just add some depth to it... by applying the Emboss heigh command... I do it three times... best effect... and set the source to the heightmap... then case a shadow using the default with a transparency of about ... 50%... ^_^ Mipmap it... and set the texture to 2... =\ Something about the UV data... it fixes skyboxes too... ^_^ Terragen is good for skyboxes...

EVERYONE LOVES THE PUFF!... =\

Wow, thanks for the help everyone.

Really makes me appreciate your heightmap even more Puffy, once I've seen all the steps you go through.

I don't really like Texture Maker, the whole interface looks too complicated and messy plus there aren't any really decent instructions lol. I think I see what you mean though but I don't know how you'd use that as a texture (mine came out as a puffy cloudy looking image) o_O
