Go ahead, open Powerpoint and insert a text box with any text that you like to transform into a 3D title. Mine is 3D PPT and I changed its color and font before to purple and Arial.
You can then select the text box and go to the Format Tab > Text Effects > 3D Rotation and choose your desired 3D format.
The text will start to take on a 3D format but it has not depth yet. To add depth to your text, highlight the text and then right click. Choose the Format Text Effects option which will bring up a dialog box. Click on the 3-D Options in the left side of the dialog box.
That's Right click > Format Text Effects > 3-D Options.
Now, find the Depth option and enter a value somewhere between 10 to 50. Change the number when you see your desired depth of the text. You can also change the angle of the lighting and the type of material for your 3D text.
Finally, you have created a 3D text using Microsoft Powerpoint only. You can animate your text for more awesome effects.
