HARDWARE USED: Amd K6 500Mhz 128 Meg RAM IMAGE DESCRIPTION: The Lone Star Tick: Amblyomma Americanum DESCRIPTION OF HOW THIS IMAGE WAS CREATED: This is my seventh entry. I wanted to do something straight on topic. Most of my pictures have been an unique interpolation or try to be. I wanted to do a relative simple object and concentrate on the textures. In that respect this picture did what I wanted. I spent a lot of time doing research for this scene. I searched the internet, that's where I found the type of ticks we have around our place. I caught a few put them under a microscope. (had to fix some lights for that microscope) The first two tick I caught where the Lone Star type. But I had trouble finding more of that type. It was amazing how many different kind of ticks there where. Dog ticks, Deer ticks, young ones, old ones, fat ones, starved ones, before I knew a month has gone by and all I had done where a few sketches. SCENE : size: 800 * 600 I used focal blur with 2 for the armature, 20 for the sample rate and confidence of .99. Objects: Lights: 2, one shadow less Tick: uses all CSG body: flatten sphere clipped by a box and pigmented with an image map legs: I tested several lathe objects intersected together and use the best 3. For hairs, I use cones place randomly there are 3 different legs types, the top, middle legs, and the tips the legs where place using my spline macro each leg had its own array for rotating head: 4 cones in a transparent cylinder leaf: a CSG using an height field and a prism the height field gives the leaf a bend and some grain the main grain or ripple effect was made with the normal the center vane was done with pigment when done without blur it was tight, with blur it grew wider but I still like the effect Background: 2 height fields one with transparency in its color_map there is only one height field GIF scaled by 200,5,200 then I place 2 copies one below the other and rotated both using gradient y pattern with different color maps after I did a test render, it needed something, so I added a few cylinders and spheres Zip-File: tick.zip is 204k long and should have everything needed to duplicate TICK contains: tick.pov tick.ini // will have to be changed for you system bugleg3.lat // lathes for legs bugleg2.lat grass2.prm // prism for grass grass4.gif //200*200 for grass wild.gif // 200*200 for background tick.tga // 200*200 image_map for tick Epilogue: This last two months have been hectic. Between work (the house from hell) spring cleaning, truck troubles, computer upgrades, I had little time for this picture. But it always in the background. When I've done scene before I'd have a solid week to set it up. Then the rest of the two months to tinker. This was a new experience for me. This also the first time I use POVwin. I can't say enough good things about it. But I do want to thank the POV team for a truly superb program! Feel free to E-mail me with any comments and or suggests.
