The circles thing is easy enough. Notice that the isometric circle is simply an ellipse. All you need to do is get it the right size and get it centered within the isometric square. What I do is make an isometric line going from the center of the square off through the the upper left edge, then I just start trying ellipses from various points on that line (outside the square) until a find the right one (that creates an ellipse that fits into the square almost exactly). Also, the width and height of the ellipse is about 70% of the width and height of the isometric square (2D diamond) that contains it. Another interesting thing is that the rectangle made up by the four points where the ellipse meets the containing diamond is width-to-height proportioned 2-to-1 -and- the width of it is the same as the height of the containing diamond. I did one while making this post and the diamond is 254x127, the ellipse inside is 176x89, and the rectangle made by the four overlapping points is 127x63. Hope that helps.
I'm having real difficulty creating isometric grids. If I try to use the line tool, I can only snap to 45degrees, horizontal and vertical. If I try to skew or transform height, photoshop anti-alias's the line and it becomes blurred. Other than this, the only method available to me is drawing pixel by pixel. VERY TEDIOUS.
Any suggestions/help? Please??
I'm new to pixel art, but am naturally creative and resonabley competant with photoshop, so this is very frustrating.
i love pixel art but im new to it. but this tutorial is really helpful but can i ask when you do like the basic cube and pyramids do you go into zoomed in view to make them really accurate?
