How to draw cast shadow in perspective drawing - Shadow Perspective Drawing

Hey everyone, today we will learn the method to draw cast shadow in perspective drawing. Basically when we draw any object with the help of perspective method there is need to draw cast shadow for object in right shape. Cast Shadow forms when the light not passes from object and form a shadow behind the object in opposite side of light source. So let's each process step by step how cast shadow drawn in rectangular box.

First step : Draw Rectangular Box with the help of Two point perspectives

In first step friend's we draw any object. So here I am choosen to draw rectangular box so you can learn cast shadow drawing method easily. First you need to draw one horizon line in the middle. After that take two vanishing point at each different side. Draw two lines first from both side by maintaining some gap and intersect it. Draw straight line between the two intersection point. Then draw two straight vertical lines at both side and also draw third line from both points according to the above image.

Second step : Draw Lines from Light Source to the top three corner

Here in second step we will draw straight vertical line from horizon line. This line is one of the most important part of cast Shadow drawing method because how much this line is taller it will make shorter shadow or how much shorter it will make shadow taller and bigger. When light source line drawn we draw lines from upper light source to the top corners of the object. Here you can see in above image how I drawn lines to the top three corners of rectangular box.

Third Step : Draw Lines from Light Source to lower three Corners of Box

In third step friend's we will draw lines from the lower point of straight vertical line of light source to the lower three corners of box. Now here we will see lines from upper light source and lines from lower light source intersecting. Then we draw lines between the intersecting point. You will able to get outline of shadow of cast shadow for the rectangular box.

Four step : Draw the areas of Cast Shadow

At last step friend's we will do shading of cast shadow. Here you need to take care that colour the cast shadow with different shades. Just like here I have shaded darker on that portion where there is no chance of light source and do shading lighter to those portion where some light source available.

So I hope friend's you enjoyed and able to understand each and every process easily. For to learn more in drawing and art subject Follow and if you like it Share our work.
