Crystal Graphics Image


320 x 352 pixels, produced on a Vic-20 computer.

An image made from a combination of a 3D wireframe drawing and tone applied using manual editing. Much use was made of the graphic system's magnify view, and moving around the image using a grid set at 3 x 3. The image was saved and loaded regularly, and worked on manually over several days.

Crystal Graphics - Stage 1

320 x 352 pixels, produced on a Vic-20 computer.

A perspective wireframe image in an appropriate position was drawn and saved from the large screen.

Crystal Graphics - Stage 2


320 x 352 pixels, produced on a Vic-20 computer.

Using a 3 x 3 grid to move around the screen in a regular manner, I applied a basic tone pattern by storing a halftone unit and then rendering it from appropriate cursor positions. There is a wonderful precision working in this way on a bitmap screen that is basically a large regular array 320 units by 352 units.

Crystal Graphics - Stage 3


320 x 352 pixels, produced on a Vic-20 computer.

I produced a tonal strip down the left hand side of the image to create a gradient from dark to light, by changing the halftone units used. I then repeated that strip across the whole background, avoiding regions close to the drawing. The regions close to the drawing were manually modified pixel by pixel to get an even finish.

The lettering was entered manually, after applying grids over "Letraset" lettering (something I was familiar with after my background in the Graphic Arts).

Crystal Graphics - Stage 4


320 x 352 pixels, produced on a Vic-20 computer.

I manually removed the lines (pixel by pixel) that should be hidden from the front faces. This produced a drawing of a 'solid' model.

Crystal Graphics - Stage 5


320 x 352 pixels, produced on a Vic-20 computer.

I entered halftone patterns over the faces of the crystal. I used a hand drawing on paper to help work out what levels of tone would be appropriate to apply.

Crystal Graphics - Final Stage


320 x 352 pixels, produced on a Vic-20 computer.

The lines defining the drawing of the crystal were removed and the halftone patterns extended where appropriate. There was a lot of manual editing, but the screen allows the user to make as many changes as they need to, without losing its precision.
