The images below link to PNG files for the texture maps which contain alpha
channels (transparency). The width and height below indicate the real-life aspect
ratio and size (in meters) for constructing the billboard; the textures themselves have
been resized to convenient powers of 2.
I am placing these texture maps into the public domain; if you want higher resolutions or
have any other questions or feedback, please contact me.

Plant: Coffee
Width: 1.6 m
Height: 1.8 m
Notes: A mature plantation specimen. Younger coffee plants have a
single main trunk. This one has been pruned back multiple times. Photo taken
in Holualoa. |
|
Plant: Coffee (leaf)
Notes: 128x256 PNG with alpha |
|
Plant: Fountain grass
Width: 1.0 m
Height: 0.8 m
Notes: Taken in a dry area. When more moisture is present, the
plant is greener and may have many more flowering tassels. |
|
Plant: Hapu‘u (tree fern)
Width: 3.2 m
Height: 3.2 m
Notes: A manicured plant from a landscaped yard, note the absence of any dead
branches. |
|
Plant: Hapu‘u (tree fern)
Width: 3.0 m
Height: 3.0 m
Notes: A wild specimen from a badly-taken photograph, color accuracy is poor and
trunk is obscured. |
|
Plant: Kiawe (mesquite)
Width: 5.0 m
Height: 4.0 m
Notes: A very difficult plant to create a texture for!
The leaves are tiny, making the digitization blurry and edge following
impossible. The result is a fairly bad texture. |
|
Plant: Kiawe (mesquite)
Width: 3.0 m
Height: 3.5 m
Notes: Same problems as other kiawe texture.
It's made more difficult by the fact that this desert plant's thin
branches "silhouette" against the bright sky. |
|
Plant: Koa
Width: 4.0 m
Height: 5.0 m
Notes: Taken from a young tree in my driveway, a good quality texture, well lit
and decent color balance. |
|
Plant: Koa Haole
Width: 2.0 m
Height: 2.0 m
Notes: A desert tree similar to kiawe, but smaller. Shares the same
problems as kiawe (small leaves, hard to photograph and extract.) |
|
Plant: Mamane
Width: 3.0 m
Height: 3.0 m
Notes: The beautiful yellow blossoms aren't very visible here,
but it's a lovely endangered tree. |
|
Plant: Ohi‘a
Width: 1.5 m
Height: 2.0 m
Notes: Young ohi‘a found growing on fairly new lava flow on the dry side
of the island. |
|
Plant: Ohi‘a
Width: 2.0 m
Height: 3.0 m
Notes: Young Ohi‘a found growing on fairly new lava flow on the dry side
of the island. |
|
Plant: Ohi‘a
Width: 4.5 m
Height: 9.0 m
Notes: Mature ohi‘a tree growing near Kilauea lookout on dry, dusty soil,
mostly cinder. Many of the smaller branches got lost in the extraction process, but
it's still a fairly good texture. |
|
Plant: Ohi‘a
Width: 5.0 m
Height: 7.5 m
Notes: Another ohi‘a from the dry side of the Kilauea area. I
didn't manage to fully remove the sky background color despite hours of pixel-by-pixel
editing, but it looks OK on a billboard. |
|
Plant: Olapa
Width: 1.0 m
Height: 2.0 m
Notes: Reportedly a "common shrub", but i haven't actually
identified one in the wild; this was extracted from a found photo. |
|
Plant: Papaya
Width: 2.0 m
Height: 4.0 m
Notes: I extracted this one before i developed any technique, so it's
pretty rough and ugly. Hopefully it'll get replaced at some point. |
|
Plant: Papaya (leaf)
Width: around 30 cm
Height: around 30 cm
Notes: This is the largest leaf from an adult tree; the smaller leaves
are highly similar, just scaled down. |
|
Plant: Papaya (bark)
Notes: 128x256 PNG, made to be wrapped once around the trunk, tileable in
both directions |
|
Plant: Strawberry Guava
Width: 0.75 m
Height: 3.0 m
Notes: Grows in clumps, almost never in isolation. I had to cut
this specimen down and photograph it in sections. The plant is thin and tall because
it was competing with all the other plants around it for sunlight. |
