opengl – Methods to apply shadows on an animated mannequin

I’ve adopted the learnopengl.com tutorial on skeletal animation, but it surely doesn’t apply shadow on the animated mannequin.

Right here is my try: shadow seems too quickly on some elements of the mannequin, and doesn’t seem as a straight line because it ought to.

Right here is the vertex shader that’s used to show the character. I believe that FragPosLightSpace shouldn’t be calculated correctly, because it’s the one variable that’s used solely to calculate the shadow within the fragment shader (if different variables have been flawed, I believe the mannequin would not show correctly).

#model 330 core

format(location = 0) in vec3 aPos;
format(location = 1) in vec3 aNormal;
format(location = 2) in vec2 aTexCoords;
format(location = 3) in ivec4 boneIds;
format(location = 4) in vec4 weights;

uniform mat4 projection;
uniform mat4 view;
uniform mat4 mannequin;

const int MAX_BONES = 100;
const int MAX_BONE_INFLUENCE = 4;
uniform mat4 finalBonesMatrices[MAX_BONES];

uniform mat4 lightSpaceMatrix;

// Output
out vec3 FragPos;
out vec3 Regular;
out vec2 TexCoords;
out vec4 FragPosLightSpace;

void predominant()
{
  mat4 boneTransform = finalBonesMatrices[boneIds[0]] * weights[0];
  boneTransform += finalBonesMatrices[boneIds[1]] * weights[1];
  boneTransform += finalBonesMatrices[boneIds[2]] * weights[2];
  boneTransform += finalBonesMatrices[boneIds[3]] * weights[3];

  vec4 totalPosition = boneTransform * vec4(aPos, 1.0);

  gl_Position =  projection * view * mannequin * totalPosition;

  TexCoords = aTexCoords;

  vec4 NormalL = boneTransform * vec4(aNormal, 0.0);

  Regular = (mannequin * NormalL).xyz; 

  FragPos = (mannequin * totalPosition).xyz; 

  FragPosLightSpace = lightSpaceMatrix * vec4(FragPos, 1.0); 
}

Thanks for any assist!
