In order to create the textures needed to make the holodeck, I first had to create a texture tile, this is a breakdown of the steps taken, this texture was drawn in Photoshop and requires some ability with an art brush to complete it. It is not formulaic so the screen shots are done at various stages along the drawing process.

Step 1 Create a Boarder

Tile 1 First step is to create a new document with a black background layer.

Next I created a boarder, this uses the technique of using dark and lighter lines to create the impression of light and dark and make a 3D effect around the frame. The boarder is made to appear to be made from metal using a texture made from several different tones of grey.

Step 2 Draw in the nut area at the top right

Tile 2 To create the appearance of a fixing holding the grate down I drew in a circular stud and lug in the corner, using varying tones of grey I create a sense of 3D again here.

Step 3 Draw the nut area at the top left

Tile 3 Repeat the above in the top left

Step 4 Draw the third nut area

Tile 4 And again in the bottom left

Step 5 Draw the last nut area

Tile 5 And lastly in the bottom right

Step 6 Add the cross spar

Tile 6 I add ed in the cross spar, to make this work I used a similar fill to the boarder using a mix of several grey tones in a fairly random pattern. I used darker tones to create the lower edges and lighter tones to create the higher edges the effect of this is to create the impression of a chamfered bar with a 3D appearance.

Step 7 Add the diamond pad in the center

Tile 7 Using the same techniques and tones as the cross bar I created a diamond shaped center pad

Step 8 Start to create the mesh grid

Tile 8 In this step I begin to create the hexagonal grid that fills the tile, I used the polygon tool set to six sides to create two guide shapes I moved this around and painted in the grid on a different layer using different shades of grey to again give the illusion of 3D

Step 9 Finish the Grid

Tile 9 In this step I finished the grid, I confess I made a slight mistake on the size of the hexagons by not allowing a couple of pixels for the shading this meant that I had to create a squashed row of hexagons to fit the tile. The end result actualy looks quite deliberate and I liked the effect so much I did not fix the error.

Step 10 Switch on the LAZORS!

Tile 10 Yes the spelling was deliberate its a play on Austin Powers!

Back to the explanation, I created a line using several layers of successively lighter green, on the outer layers I reduced the opacity and used a very soft brush to create the appearance of a fading glow.

The line was then placed on the bottom edge of the page.

Step 11 Add the second green line

Tile 11 I duplicated the green line and rotated it through 90 degrees, I then moved it to the right edge.

  Step 12 Add the third green line

Tile 12 Duplicated the vertical line and moved it to the left edge

  Step 13 Finish the light effect

Tile 13 Repeat and move to the top to complete the lighting effect

Step 14 Using the tile

Tile 14 The finished tile can be duplicated on a larger canvas to create a tiled texture, you can see how the green lines join to produce the desired effect.
