C++ (Cpp) GLSLProgram::unUse Examples

Example #1

File: HelloGLSL.cpp Project: henrya2/OpenGL-Samples

void HelloGLSL::onRender()
{
    glslProgram.use();

    glBindVertexArray(vao);

    glDrawArrays(GL_TRIANGLES, 0, 3);

    glslProgram.unUse();
    glBindVertexArray(0);
}

Example #2

File: OgroInvasion.cpp Project: henrya2/OpenGL-Samples

void OgroInvasion::onRender()
{
	glslProgram.use();

	glBindVertexArray(vaoID);

	glDrawElements(GL_TRIANGLES, 6, GL_UNSIGNED_SHORT, nullptr);

	glBindVertexArray(0);

	glslProgram.unUse();
}
