How to create a Mesh Object

Part 1 Setting the Mesh Folder path in J Wildfire 3.31

1. Locate your C: directory and create a folder that you name JWFPATH. Create another folder inside JWFPATH and name it MESH.

2. The path should be C:JWFPATHMESH (Note – You can create a folder path anywhere you want, what is important is that you remember where it is located.

3. Create one more folder anywhere on your computer and call it Mesh Slices. Example path could be C:LibraryPicturesMesh Slices. Just remember where it is located. This is where your Mesh Slice images are generated to.

Setting the MESH path in J Wildfire Preference Tab

1. Click on the Preference Tab. The preference box opens. Your box will show a lot of setting choices. Locate the line that indicates tinaMeshPath.

2. Click opens the box and type in the same path that you created for your MESH. C:JWFPATHMESH. J Wildfire can now store all your final Mesh Obj here.

Note: What you type in has to be accurate and must match 100% to the actual folder path.

Part 2 Creating a Simple Solid for Mesh Generation

1. Click new from scratch

2. Click Add and change linear3d to obj_mesh primitive id0 (default variable). You now have a sphere.

3. Go to the camera tab and set zoom=2 & pix per unit to 150

4. Then toggle the 3D button to enable a solid look. This also enables lighting. No need to adjust any lighting yet.

Add a post enabled variation effect to your obj_mesh Primitive id0

1. Make sure the 3d button is still toggled on.

2. Go to the camera tab and make sure

3. Zoom is set to 2, Pix per unit = 150 and set pitch to 45

4. Select variation 2 on transform 1. Click the triangle flag and opens the variation list. Select Fan2 and depress the little box to the right of Fan2 names. This toggle it to a post transform. Clicking the post transform will eliminate the blurry effect. Now set the fan2 main variable to 0.332 x=-0.3 and y=3.3, you should have an image that looks like the one below.

5. Do a quick render to see a solid shape. Go ahead and render a final.

Part 3 More tweaks to the simple solid for Mesh Generation

1. Larger holes are better for Mesh! Let’s change the value of the Fan2 variables. Set Fan2 x=0.8 y=0.6

2. Change pitch to 0. This will set it to a top view.

1. Click the left param triangle on Obj Mesh prim. This opens the list of variables. Locate variable subdiv_level. If you are using a laptop – Set the subdiv_level variable to 2. If you are using a high end performance desk top, set it to 4.

2. Set your gradient to the systems (south-sea-bather) on the gradient tab.

3. Do a quick render and final render to save your work at this step.

Part 4 Creating the Voxel stack Slices

This is where all the main work gets done. You will notice 3 windows. The first one gives you the top view. The second one is your side view. The third gives you a perspective view.

1. Click the 3D Mesh button to open Mesh Generation panel. You can also access the panel by clicking windows>Fractal flames: Mesh Generator.

2. This box allows you to set the range of where the slicing occurs. Drag Position 1 – (yellow) line to where it is just barely touching the top. I always leave a fraction hairline space between the object and the line. Drag Position 2 – (green) line just below the object. Take care that the lines do not touch the object. You will see yellow anomalies show up in the Top view and Perspective view windows if you touch the object in the Front view. If this happens, just make sure the line is just above and below the object. Leave a hairline space and you are ready to go.

3. Make sure voxel stack is selected. 4. Render quality is on 300. Go with 300 for a laptop and 400 for a desk top machine. Keep in mind that this is a simple solid being converted. More complicated fractals need more adjustments and tools. I may do an advanced tutorial on exploring the other options at a later date.

5. Click Generate to create the slices. Slices are 512 sliced png image files that will be saved to a folder you created earlier. You will have to navigate to it. Example – C:JWF Mesh slices

1. When you click the generate button a (save dialog box opens. Navigate to a folder where you wanted to generate your 512 image files to. Example: I clicked the up folder icon to see where my folder was in the directory tree. You can start from C: and navigate down to where your folder is at. Example: Mine is located C:JWF Mesh Slices.

2. The new folder can be created by clicking the yellow folder in the center top area of the dialog bog. I named this new mesh slice subfolder Fan2 Bubble.

3. Now click open that new subfolder Fan2 Bubble. (Note – do not type anything for a file name just yet. Scroll down for that step 🙂

1. Click into the File name: type “Fan2 Bubble”. Click the save button and this will start generating the 512 png files. It will take 30 to 40 minutes on a laptop with 8 gb of memory and less than 10 to 20 minutes on a quad core Intel Pc desktop.

1. Keep an eye on the progress bar as the png files are generated. It will be complete when it reaches 100%. (Do not close the window)

2. We are done this part of the tutorial! Click the Mesh Generation tab to continue. You will need to down load the next tutorial Part 5 Generating the Mesh Object. Take a break if your over whelmed! Go ahead and close everything and you continue with the last part of this tutorial series. Don’t worry, your 512 png files are saved! We can retrieve them in the next tutorial.

Part 5 Generating the MESH Object

1. Your progress bar should have been 100% in Part 4 (How to create the voxel stack slices)

2. Click on the Mesh Generator tab to open the dialog box. Note – Its ok if you see 3 blank screens if you closed your program after Part 4. Scroll down 🙂

1. Click – Load sequence

2. A Dialog box opens. Navigate to find your MESH slice folder (Your named folder that has your 512 png slice image’s. Open the folder. Example of my path: C: JWF Mesh slices Fan2 Bubble.

3. Click Open when you find your subfolder named Fan2 Bubble. Opening it will reveal all 512 slice image files.

1. Watch the progress bar as your Mesh Wavefront Obj is created. A window viewer will open when the progress bar reaches 100%. Your actual MESH will appear in the Windows Viewer.

2. The MESH will look fuzzy at first. You can move it around by mouse dragging each of the variable cells or simply click the up & down arrows. Click the Refresh view button to make it solid. Keep in mind that this is just a viewer to look at your finished work. You can now do several things with your MESH.

A. Import into any software that supports Wavefront Obj files. Scroll down to see the list of software the supports Wavefront Obj. Files. Keep on scrolling 🙂

Taubin smooth was not used for this tutorial. So your image may differ slightly than the one pictured here. Taubin Smooth will be explored in a future tutorial.
